Summary: Domain Name System (DNS) Server (named) |
Berkeley Internet Name Domain (BIND) is an implementation of the Domain Name System (DNS) protocols and provides an openly redistributable reference implementation of the major components of the Domain Name System. This package includes the components to operate a DNS server.
MPL-2.0
* Fri Aug 23 2024 Jorik Cronenberg <jorik.cronenberg@suse.com> - Update to release 9.20.1 New Features: * Implement rndc retransfer -force. * A new optional argument -force has been added to the command rndc retransfer. When it is specified, named aborts the ongoing zone transfer (if there is one) and starts a new transfer. * dig now reports a missing QUESTION section for messages with opcode QUERY. * Query responses should contain the QUESTION section, with some exceptions. dig was not reporting this. Feature Changes: * Tighten max-recursion-queries and add max-query-restarts configuration statement. * There were cases when the max-recursion-queries quota was ineffective. It was possible to craft zones that would cause a resolver to waste resources by sending excessive queries while attempting to resolve a name. This has been addressed by correcting errors in the implementation of max-recursion-queries and by reducing the default value from 100 to 32. * In addition, a new max-query-restarts configuration statement has been added, which limits the number of times a recursive server will follow CNAME or DNAME records before terminating resolution. This was previously a hard-coded limit of 16 but is now configurable with a default value of 11. * ISC would like to thank Huayi Duan, Marco Bearzi, Jodok Vieli, and Cagin Tanir from NetSec group, ETH Zurich for discovering and notifying us about the issue. * Allow shorter resolver-query-timeout configuration. * The minimum allowed value of resolver-query-timeout was lowered from its previous value of 10 000 milliseconds (which is still the default) to 301 milliseconds. Note however that values of 1 to 300 inclusive are interpreted as seconds before applying the limit. A value of zero is interpreted as the default. * Raise the log level of priming failures. * When a priming query is complete, it was previously logged at level DEBUG(1), regardless of success or failure. It is now logged to NOTICE in the case of failure. Bug Fixes: * Fix a crash caused by valid TSIG signatures with invalid time. * An assertion failure was triggered when the TSIG had a valid cryptographic signature but the time was invalid. This could happen when the times between the primary and secondary servers were not synchronised. The crash has now been fixed. * Return SERVFAIL for a too long CNAME chain. * When following long CNAME chains, named was returning NOERROR (along with a partial answer) instead of SERVFAIL, if the chain exceeded the maximum length. This has been fixed. * Reconfigure catz member zones during named reconfiguration. * During a reconfiguration, named wasn’t reconfiguring catalog zones’ member zones. This has been fixed. * Update key lifetime and metadata after dnssec-policy reconfiguration. * Adjust key state and timing metadata if dnssec-policy key lifetime configuration is updated, so that it also affects existing keys. * Fix a crash during zone modification. * Fix an assertion failure that could happen when an authoritative zone was modified while the server was generating an answer from that zone. * Fix assertion failure when executing named-checkconf -v to print its version. * Fix generation of 6to4-self name expansion from IPv4 address. * The period between the most significant nibble of the encoded IPv4 address and the 2.0.0.2.IP6.ARPA suffix was missing, resulting in the wrong name being checked. This has been fixed. * dig +yaml was producing unexpected and/or invalid YAML. output. * SVBC ALPN text parsing failed to reject zero-length ALPN. * Fix false QNAME minimisation error being reported. * Remove the false positive success resolving log message when QNAME minimisation is in effect and the final result is an NXDOMAIN. * Fix --enable-tracing build on systems without dtrace. * A missing util/dtrace.sh file prevented builds on systems without the dtrace utility. This has been corrected. * Wed Jul 24 2024 Jorik Cronenberg <jorik.cronenberg@suse.com> - Update to new major version 9.20.0 For a complete list of all changes see: * https://bind9.readthedocs.io/en/v9.20.0/notes.html * The CHANGES file in the source RPM Some noteworthy changes: * Added new BuildRequires liburcu for lock free data structures. * A new DNSSEC tool dnssec-ksr has been added to create Key Signing Request (KSR) and Signed Key Response (SKR) files. * /etc/bind.keys and /var/lib/named/named.root.key have been removed as the correct defaults are pre-compiled and there is no need to configure bind.keys manually. * The functions that were in the libbind9 shared library have been moved to the libisc and libisccfg libraries. The now-empty libbind9 has been removed and is no longer installed. * The irs_resconf module has been moved to the libdns shared library. The now-empty libirs library has been removed and is no longer installed. Security Fixes: * A malicious DNS client that sent many queries over TCP but never read the responses could cause a server to respond slowly or not at all for other clients. This has been fixed. (CVE-2024-0760) [bsc#1228255] * It is possible to craft excessively large resource records sets, which have the effect of slowing down database processing. This has been addressed by adding a configurable limit to the number of records that can be stored per name and type in a cache or zone database. The default is 100, which can be tuned with the new max-records-per-type option. * It is possible to craft excessively large numbers of resource record types for a given owner name, which has the effect of slowing down database processing. This has been addressed by adding a configurable limit to the number of records that can be stored per name and type in a cache or zone database. The default is 100, which can be tuned with the new max-types-per-name option. (CVE-2024-1737) [bsc#1228256] * Validating DNS messages signed using the SIG(0) protocol (RFC 2931) could cause excessive CPU load, leading to a denial-of-service condition. Support for SIG(0) message validation was removed from this version of named. (CVE-2024-1975) [bsc#1228257] * Due to a logic error, lookups that triggered serving stale data and required lookups in local authoritative zone data could have resulted in an assertion failure. This has been fixed. * Potential data races were found in our DoH implementation, related to HTTP/2 session object management and endpoints set object management after reconfiguration. These issues have been fixed. * When looking up the NS records of parent zones as part of looking up DS records, it was possible for named to trigger an assertion failure if serve-stale was enabled. This has been fixed. (CVE-2024-4076) [bsc#1228258] * Fri May 17 2024 Jorik Cronenberg <jorik.cronenberg@suse.com> - Update to release 9.18.27 New Features: * A new option signatures-jitter has been added to dnssec-policy to allow signature expirations to be spread out over a period of time. Feature Changes: * DNSSEC signatures that are not valid because the current time falls outside the signature inception and expiration dates are skipped instead of causing an immediate validation failure. * Sun Apr 21 2024 Jorik Cronenberg <jorik.cronenberg@suse.com> - Update to release 9.18.26 New Features: * The statistics channel now includes counters that indicate the number of currently connected TCP IPv4/IPv6 clients. * Added RESOLVER.ARPA to the built in empty zones. Bug Fixes: * Changes to listen-on statements were ignored on reconfiguration unless the port or interface address was changed, making it impossible to change a related listener transport type. That issue has been fixed. * A bug in the keymgr code unintentionally slowed down some DNSSEC key rollovers. This has been fixed. * Some ISO 8601 durations were accepted erroneously, leading to shorter durations than expected. This has been fixed. * Wed Mar 20 2024 Jorik Cronenberg <jorik.cronenberg@suse.com> - Update to release 9.18.25 Bug Fixes: * A regression in cache-cleaning code enabled memory use to grow significantly more quickly than before, until the configured max-cache-size limit was reached. This has been fixed. * Using rndc flush inadvertently caused cache cleaning to become less effective. This could ultimately lead to the configured max-cache-size limit being exceeded and has now been fixed. * The logic for cleaning up expired cached DNS records was tweaked to be more aggressive. This change helps with enforcing max-cache-ttl and max-ncache-ttl in a timely manner. [GL #4591] * It was possible to trigger a use-after-free assertion when the overmem cache cleaning was initiated. This has been fixed. * Tue Feb 13 2024 Jorik Cronenberg <jorik.cronenberg@suse.com> - Update to release 9.18.24 Security Fixes: * Validating DNS messages containing a lot of DNSSEC signatures could cause excessive CPU load, leading to a denial-of-service condition. This has been fixed. (CVE-2023-50387) [bsc#1219823] * Preparing an NSEC3 closest encloser proof could cause excessiv CPU load, leading to a denial-of-service condition. This has been fixed. (CVE-2023-50868) [bsc#1219826] * Parsing DNS messages with many different names could cause excessive CPU load. This has been fixed. (CVE-2023-4408) [bsc#1219851] * Specific queries could cause named to crash with an assertion failure when nxdomain-redirect was enabled. This has been fixed. (CVE-2023-5517) [bsc#1219852] * A bad interaction between DNS64 and serve-stale could cause named to crash with an assertion failure, when both of these features were enabled. This has been fixed. (CVE-2023-5679) [bsc#1219853] * Query patterns that continuously triggered cache database maintenance could cause an excessive amount of memory to be allocated, exceeding max-cache-size and potentially leading to all available memory on the host running named being exhausted This has been fixed. (CVE-2023-6516) [bsc#1219854] * Under certain circumstances, the DNS-over-TLS client code incorrectly attempted to process more than one DNS message at a time, which could cause named to crash with an assertion failure. This has been fixed. Bug Fixes: * The counters exported via the statistics channel were changed back to 64-bit signed values; they were being inadvertently truncated to unsigned 32-bit values since BIND 9.15.0. * Thu Jan 04 2024 Jorik Cronenberg <jorik.cronenberg@suse.com> - Update to release 9.18.21 Removed Features: * Support for using AES as the DNS COOKIE algorithm (cookie-algorithm aes;) has been deprecated and will be removed in a future release. Please use the current default, SipHash-2-4, instead. * The resolver-nonbackoff-tries and resolver-retry-interval statements have been deprecated. Using them now causes a warning to be logged. * Wed Nov 15 2023 Jorik Cronenberg <jorik.cronenberg@suse.com> - Update to release 9.18.20 Feature Changes: * The IP addresses for B.ROOT-SERVERS.NET have been updated to 170.247.170.2 and 2801:1b8:10::b. Bug Fixes: * If the unsigned version of an inline-signed zone contained DNSSEC records, it was incorrectly scheduled for resigning. This has been fixed. * Looking up stale data from the cache did not take local authoritative data into account. This has been fixed. * An assertion failure was triggered when lock-file was used at the same time as the named -X command-line option. This has been fixed. * The lock-file file was being removed when it should not have been, making the statement ineffective when named was started three or more times. This has been fixed. * Fri Oct 13 2023 Thorsten Kukuk <kukuk@suse.com> - Disable SLP by default for Factory and ALP (bsc#1214884) * Tue Sep 19 2023 Jorik Cronenberg <jorik.cronenberg@suse.com> - Update to release 9.18.19 Security Fixes: * Previously, sending a specially crafted message over the control channel could cause the packet-parsing code to run out of available stack memory, causing named to terminate unexpectedly. This has been fixed. (CVE-2023-3341) [bsc#1215472] * A flaw in the networking code handling DNS-over-TLS queries could cause named to terminate unexpectedly due to an assertion failure under significant DNS-over-TLS query load. This has been fixed. (CVE-2023-4236) [bsc#1215471] Removed Features: * The dnssec-must-be-secure option has been deprecated and will be removed in a future release. Feature Changes: * If the server command is specified, nsupdate now honors the nsupdate -v option for SOA queries by sending both the UPDATE request and the initial query over TCP. Bug Fixes: * The value of the If-Modified-Since header in the statistics channel was not being correctly validated for its length, potentially allowing an authorized user to trigger a buffer overflow. Ensuring the statistics channel is configured correctly to grant access exclusively to authorized users is essential (see the statistics-channels block definition and usage section). * The Content-Length header in the statistics channel was lacking proper bounds checking. A negative or excessively large value could potentially trigger an integer overflow and result in an assertion failure. * Several memory leaks caused by not clearing the OpenSSL error stack were fixed. * The introduction of krb5-subdomain-self-rhs and ms-subdomain-self-rhs UPDATE policies accidentally caused named to return SERVFAIL responses to deletion requests for non-existent PTR and SRV records. This has been fixed. * The stale-refresh-time feature was mistakenly disabled when the server cache was flushed by rndc flush. This has been fixed. * BIND’s memory consumption has been improved by implementing dedicated jemalloc memory arenas for sending buffers. This optimization ensures that memory usage is more efficient and better manages the return of memory pages to the operating system. * Previously, partial writes in the TLS DNS code were not accounted for correctly, which could have led to DNS message corruption. This has been fixed. * Mon Sep 11 2023 Pedro Monreal <pmonreal@suse.com> - Enable crypto-policies support: [bsc#1211301] * Rebase vendor-files/config/named.conf * Wed Aug 16 2023 Jorik Cronenberg <jorik.cronenberg@suse.com> - Update to release 9.18.18 Feature Changes: * When a primary server for a zone responds to an SOA query, but the subsequent TCP connection required to transfer the zone is refused, that server is marked as temporarily unreachable. This now also happens if the TCP connection attempt times out, preventing too many zones from queuing up on an unreachable server and allowing the refresh process to move on to the next configured primary more quickly. * The dialup and heartbeat-interval options have been deprecated and will be removed in a future BIND 9 release. Bug Fixes: * Processing already-queued queries received over TCP could cause an assertion failure, when the server was reconfigured at the same time or the cache was being flushed. This has been fixed. * Setting dnssec-policy to insecure prevented zones containing resource records with a TTL value larger than 86400 seconds (1 day) from being loaded. This has been fixed by ignoring the TTL values in the zone and using a value of 604800 seconds (1 week) as the maximum zone TTL in key rollover timing calculations. * Wed Jul 19 2023 Jorik Cronenberg <jorik.cronenberg@suse.com> - Update to release 9.18.17 Feature Changes: * If a response from an authoritative server has its RCODE set to FORMERR and contains an echoed EDNS COOKIE option that was present in the query, named now retries sending the query to the same server without an EDNS COOKIE option. * The relaxed QNAME minimization mode now uses NS records. This reduces the number of queries named makes when resolving, as it allows the non-existence of NS RRsets at non-referral nodes to be cached in addition to the normally cached referrals. Bug Fixes: * The ability to read HMAC-MD5 key files, which was accidentally lost in BIND 9.18.8, has been restored. * Several minor stability issues with the catalog zone implementation have been fixed. * Thu Jul 13 2023 Jorik Cronenberg <jorik.cronenberg@suse.com> - Enable dnstap support * Thu Jul 06 2023 Dirk Müller <dmueller@suse.com> - rebuild bind-utils on libuv updates (bsc#1212090) * Thu Jun 22 2023 Jorik Cronenberg <jorik.cronenberg@suse.com> - Update to release 9.18.16 Security Fixes: * The overmem cleaning process has been improved, to prevent the cache from significantly exceeding the configured max-cache-size limit. (CVE-2023-2828) * A query that prioritizes stale data over lookup triggers a fetch to refresh the stale data in cache. If the fetch is aborted for exceeding the recursion quota, it was possible for named to enter an infinite callback loop and crash due to stack overflow. This has been fixed. (CVE-2023-2911) New Features: * The system test suite can now be executed with pytest (along with pytest-xdist for parallel execution). Removed Features: * TKEY mode 2 (Diffie-Hellman Exchanged Keying) is now deprecated, and will be removed in a future release. A warning will be logged when the tkey-dhkey option is used in named.conf. Bug Fixes: * BIND could get stuck on reconfiguration when a listen-on statement for HTTP is removed from the configuration. That has been fixed. * Previously, it was possible for a delegation from cache to be returned to the client after the stale-answer-client-timeout duration. This has been fixed. * BIND could allocate too big buffers when sending data via stream-based DNS transports, leading to increased memory usage. This has been fixed. * When the stale-answer-enable option was enabled and the stale-answer-client-timeout option was enabled and larger than 0, named previously allocated two slots from the clients-per-query limit for each client and failed to gradually auto-tune its value, as configured. This has been fixed. * Wed May 17 2023 Jorik Cronenberg <jorik.cronenberg@suse.com> - Update to release 9.18.15 Bug Fixes: * The max-transfer-time-in and max-transfer-idle-in statements have not had any effect since the BIND 9 networking stack was refactored in version 9.16. The missing functionality has been re-implemented and incoming zone transfers now time out properly when not progressing. * The read timeout in rndc is now 60 seconds, matching the behavior in BIND 9.16 and earlier. It had previously been lowered to 30 seconds by mistake. * When the ISC_R_INVALIDPROTO (ENOPROTOOPT, EPROTONOSUPPORT) error code is returned by libuv, it is now treated as a network failure: the server for which that error code is returned gets marked as broken and is not contacted again during a given resolution process. * When removing delegations from an opt-out range, empty-non-terminal NSEC3 records generated by those delegations were not cleaned up. This has been fixed. * Log file rotation code did not clean up older versions of log files when the logging channel had an absolute path configured as a file destination. This has been fixed. Known Issues: * Sending NOTIFY messages silently fails when the source port specified in the notify-source statement is already in use. This can happen e.g. when multiple servers are configured as NOTIFY targets for a zone and some of them are unresponsive. This issue can be worked around by not specifying the source port for NOTIFY messages in the notify-source statement; note that source port configuration is already deprecated and will be removed altogether in a future release. * Fri Apr 21 2023 Jorik Cronenberg <jorik.cronenberg@suse.com> - Update to release 9.18.14 Removed Features: * Zone type delegation-only, and the delegation-only and root-delegation-only statements, have been deprecated. A warning is now logged when they are used. * These statements were created to address the SiteFinder controversy, in which certain top-level domains redirected misspelled queries to other sites instead of returning NXDOMAIN responses. Since top-level domains are now DNSSEC-signed, and DNSSEC validation is active by default, the statements are no longer needed. Bug Fixes: * Several bugs which could cause named to crash during catalog zone processing have been fixed. * Previously, downloading large zones over TLS (XoT) from a primary could hang the transfer on the secondary, especially when the connection was unstable. This has been fixed. * Performance of DNSSEC validation in zones with many DNSKEY records has been improved. * Wed Mar 15 2023 Jorik Cronenberg <jorik.cronenberg@suse.com> - Update to release 9.18.13 New Features: * RPZ updates are now run on specialized “offload” threads to reduce the amount of time they block query processing on the main networking threads. This increases the responsiveness of named when RPZ updates are being applied after an RPZ zone has been successfully transferred. Feature Changes: * Catalog zone updates are now run on specialized “offload” threads to reduce the amount of time they block query processing on the main networking threads. This increases the responsiveness of named when catalog zone updates are being applied after a catalog zone has been successfully transferred. * libuv support for receiving multiple UDP messages in a single recvmmsg() system call has been tweaked several times between libuv versions 1.35.0 and 1.40.0; the current recommended libuv version is 1.40.0 or higher. New rules are now in effect for running with a different version of libuv than the one used at compilation time. These rules may trigger a fatal error at startup: - Building against or running with libuv versions 1.35.0 and 1.36.0 is now a fatal error. - Running with libuv version higher than 1.34.2 is now a fatal error when named is built against libuv version 1.34.2 or lower. - Running with libuv version higher than 1.39.0 is now a fatal error when named is built against libuv version 1.37.0, 1.38.0, 1.38.1, or 1.39.0. * This prevents the use of libuv versions that may trigger an assertion failure when receiving multiple UDP messages in a single system call. Bug Fixes: * named could crash with an assertion failure when adding a new zone into the configuration file for a name which was already configured as a member zone for a catalog zone. This has been fixed. * When named starts up, it sends a query for the DNSSEC key for each configured trust anchor to determine whether the key has changed. In some unusual cases, the query might depend on a zone for which the server is itself authoritative, and would have failed if it were sent before the zone was fully loaded. This has now been fixed by delaying the key queries until all zones have finished loading. * Thu Feb 16 2023 Jorik Cronenberg <jorik.cronenberg@suse.com> - Update to release 9.18.12 Removed Features: * Specifying a port when configuring source addresses (i.e., as an argument to query-source, query-source-v6, transfer-source, transfer-source-v6, notify-source, notify-source-v6, parental-source, or parental-source-v6, or in the source or source-v6 arguments to primaries, parental-agents, also-notify, or catalog-zones) has been deprecated. In addition, the use-v4-udp-ports, use-v6-udp-ports, avoid-v4-udp-ports, and avoid-v6-udp-ports options have also been deprecated. Warnings are now logged when any of these options are encountered in named.conf. In a future release, they will be made nonfunctional. Bug Fixes: * A constant stream of zone additions and deletions via rndc reconfig could cause increased memory consumption due to delayed cleaning of view memory. This has been fixed. * The speed of the message digest algorithms (MD5, SHA-1, SHA-2), and of NSEC3 hashing, has been improved. * Pointing parental-agents to a resolver did not work because the RD bit was not set on DS requests. This has been fixed. * Building BIND 9 failed when the --enable-dnsrps switch for ./configure was used. This has been fixed. - Updated keyring and signature * Tue Jan 24 2023 Jorik Cronenberg <jorik.cronenberg@suse.com> - Update to release 9.18.11 Security Fixes: * An UPDATE message flood could cause named to exhaust all available memory. This flaw was addressed by adding a new update-quota option that controls the maximum number of outstanding DNS UPDATE messages that named can hold in a queue at any given time (default: 100). (CVE-2022-3094) * named could crash with an assertion failure when an RRSIG query was received and stale-answer-client-timeout was set to a non-zero value. This has been fixed. (CVE-2022-3736) * named running as a resolver with the stale-answer-client-timeout option set to any value greater than 0 could crash with an assertion failure, when the recursive-clients soft quota was reached. This has been fixed. (CVE-2022-3924) New Features: * The new update-quota option can be used to control the number of simultaneous DNS UPDATE messages that can be processed to update an authoritative zone on a primary server, or forwarded to the primary server by a secondary server. The default is 100. A new statistics counter has also been added to record events when this quota is exceeded, and the version numbers for the XML and JSON statistics schemas have been updated. Removed Features: * The Differentiated Services Code Point (DSCP) feature in BIND has been non-operational since the new Network Manager was introduced in BIND 9.16. It is now marked as obsolete, and vestigial code implementing it has been removed. Configuring DSCP values in named.conf now causes a warning to be logged. Feature Changes: * The catalog zone implementation has been optimized to work with hundreds of thousands of member zones. Bug Fixes: * A rare assertion failure was fixed in outgoing TCP DNS connection handling. * Large zone transfers over TLS (XoT) could fail. This has been fixed. * In addition to a previously fixed bug, another similar issue was discovered where quotas could be erroneously reached for servers, including any configured forwarders, resulting in SERVFAIL answers being sent to clients. This has been fixed. * In certain query resolution scenarios (e.g. when following CNAME records), named configured to answer from stale cache could return a SERVFAIL response despite a usable, non-stale answer being present in the cache. This has been fixed. * When an outgoing request timed out, named would retry up to three times with the same server instead of trying the next available name server. This has been fixed. * Recently used ADB names and ADB entries (IP addresses) could get cleaned when ADB was under memory pressure. To mitigate this, only actual ADB names and ADB entries are now counted (excluding internal memory structures used for “housekeeping”) and recently used (<= 10 seconds) ADB names and entries are excluded from the overmem memory cleaner. * The “Prohibited” Extended DNS Error was inadvertently set in some NOERROR responses. This has been fixed. * Previously, TLS session resumption could have led to handshake failures when client certificates were used for authentication (Mutual TLS). This has been fixed. [bsc#1207471, bsc#1207473, bsc#1207475] * Wed Jan 04 2023 Thiago Macieira <thiago@kde.org> - Declare that named.service depends on network-online.target, otherwise named may start too early and thus fail (time out) when resolving some domains. This happens easily in containers. * Thu Dec 22 2022 Jorik Cronenberg <jorik.cronenberg@suse.com> - Update to release 9.18.10 Feature Changes: * To reduce unnecessary memory consumption in the cache, NXDOMAIN records are no longer retained past the normal negative cache TTL, even if stale-cache-enable is set to yes. * The auto-dnssec option has been deprecated and will be removed in a future BIND 9.19.x release. Please migrate to dnssec-policy. * The coresize, datasize, files, and stacksize options have been deprecated. The limits these options set should be enforced externally, either by manual configuration (e.g. using ulimit) or via the process supervisor (e.g. systemd). * Setting alternate local addresses for inbound zone transfers has been deprecated. The relevant options (alt-transfer-source, alt-transfer-source-v6, and use-alt-transfer-source) will be removed in a future BIND 9.19.x release. * The number of HTTP headers allowed in requests sent to named’s statistics channel has been increased from 10 to 100, to accommodate some browsers that send more than 10 headers by default. Bug Fixes: * named could crash due to an assertion failure when an HTTP connection to the statistics channel was closed prematurely (due to a connection error, shutdown, etc.). * When a catalog zone was removed from the configuration, in some cases a dangling pointer could cause the named process to crash. * When a zone was deleted from a server, a key management object related to that zone was inadvertently kept in memory and only released upon shutdown. This could lead to constantly increasing memory use on servers with a high rate of changes affecting the set of zones being served. * TLS configuration for primary servers was not applied for zones that were members of a catalog zone. * In certain cases, named waited for the resolution of outstanding recursive queries to finish before shutting down. * host and nslookup command-line options setting the custom TCP/UDP port to use were ignored for ANY queries (which are sent over TCP). * The zone <name>/<class>: final reference detached log message was moved from the INFO log level to the DEBUG(1) log level to prevent the named-checkzone tool from superfluously logging this message in non-debug mode. * Mon Nov 21 2022 Jorik Cronenberg <jorik.cronenberg@suse.com> - Update to bind release 9.18.9 Bug Fixes: * A crash was fixed that happened when a dnssec-policy zone that used NSEC3 was reconfigured to enable inline-signing. * In certain resolution scenarios, quotas could be erroneously reached for servers, including any configured forwarders, resulting in SERVFAIL answers being sent to clients. * rpz-ip rules in response-policy zones could be ineffective in some cases if a query had the CD (Checking Disabled) bit set to 1. * Previously, if Internet connectivity issues were experienced during the initial startup of named, a BIND resolver with dnssec-validation set to auto could enter into a state where it would not recover without stopping named, manually deleting the managed-keys.bind and managed-keys.bind.jnl files, and starting named again. * The statistics counter representing the current number of clients awaiting recursive resolution results (RecursClients) could overflow in certain resolution scenarios. * Previously, the port in remote servers such as in primaries and parental-agents could be wrongly configured because of an inheritance bug. * Previously, BIND failed to start on Solaris-based systems with hundreds of CPUs. * When a DNS resource record’s TTL value was equal to the resolver’s configured prefetch “eligibility” value, the record was erroneously not treated as eligible for prefetching. * Mon Nov 07 2022 Jorik Cronenberg <jorik.cronenberg@suse.com> - Update to bind release 9.18.8 New Features: * Support for parsing and validating the dohpath service parameter in SVCB records was added. * named now logs the supported cryptographic algorithms during startup and in the output of named -V. * The recursion not available and query (cache) '...' denied log messages were extended to include the name of the ACL that caused a given query to be denied. Bug Fixes: * An assertion failure was fixed in named that was caused by aborting the statistics channel connection while sending statistics data to the client. * Changing just the TSIG key names for primaries in catalog zones’ member zones was not effective. This has been fixed. Known Issues: * Upgrading from BIND 9.16.32, 9.18.6, or any older version may require a manual configuration change. The following configurations are affected: - type primary zones configured with dnssec-policy but without either allow-update or update-policy, - type secondary zones configured with dnssec-policy. In these cases please add inline-signing yes; to the individual zone configuration(s). Without applying this change, named will fail to start. For more details, see https://kb.isc.org/docs/dnssec-policy-requires-dynamic-dns-or-inline-signing * BIND 9.18 does not support dynamic update forwarding (see allow-update-forwarding) in conjuction with zone transfers over TLS (XoT). This obsoletes the following patch: * fix_documentation-Sphinx.patch * Wed Oct 05 2022 Matej Cepl <mcepl@suse.com> - Add fix_documentation-Sphinx.patch to fix building with the current Sphinx (https://gitlab.isc.org/isc-projects/bind9/-/issues/3572). - Reapply bind-ldapdump-use-valid-host.patch * Wed Sep 21 2022 Jorik Cronenberg <jorik.cronenberg@suse.com> - Update to bind release 9.18.7 Security Fixes: * Previously, there was no limit to the number of database lookups performed while processing large delegations, which could be abused to severely impact the performance of named running as a recursive resolver. This has been fixed. (CVE-2022-2795) * When an HTTP connection was reused to request statistics from the stats channel, the content length of successive responses could grow in size past the end of the allocated buffer. This has been fixed. (CVE-2022-2881) * Memory leaks in code handling Diffie-Hellman (DH) keys were fixed that could be externally triggered, when using TKEY records in DH mode with OpenSSL 3.0.0 and later versions. (CVE-2022-2906) * named running as a resolver with the stale-answer-client-timeout option set to 0 could crash with an assertion failure, when there was a stale CNAME in the cache for the incoming query. This has been fixed. (CVE-2022-3080) * Memory leaks were fixed that could be externally triggered in the DNSSEC verification code for the EdDSA algorithm. (CVE-2022-38178) Feature Changes: * Response Rate Limiting (RRL) code now treats all QNAMEs that are subject to wildcard processing within a given zone as the same name, to prevent circumventing the limits enforced by RRL. * Zones using dnssec-policy now require dynamic DNS or inline-signing to be configured explicitly. * When reconfiguring dnssec-policy from using NSEC with an NSEC-only DNSKEY algorithm (e.g. RSASHA1) to a policy that uses NSEC3, BIND 9 no longer fails to sign the zone; instead, it keeps using NSEC until the offending DNSKEY records have been removed from the zone, then switches to using NSEC3. * A backward-compatible approach was implemented for encoding internationalized domain names (IDN) in dig and converting the domain to IDNA2008 form; if that fails, BIND tries an IDNA2003 conversion. Bug Fixes: * A serve-stale bug was fixed, where BIND would try to return stale data from cache for lookups that received duplicate queries or queries that would be dropped. This bug resulted in premature SERVFAIL responses, and has now been resolved. This obsoletes the following patch: * bind-fix-mysql-bindings.patch [bsc#1203614, bsc#1203615, bsc#1203616, bsc#1203618, bsc#1203620] * Thu Aug 18 2022 Jorik Cronenberg <jorik.cronenberg@suse.com> - Fix typo in contrib/dlz/modules/{mysql,mysqldyn} that references LDAP_LIBS instead of MYSQL_LIBS. [bsc#1202149, bind.spec, bind-fix-mysql-bindings.patch] * Thu Aug 18 2022 Jorik Cronenberg <jorik.cronenberg@suse.com> - Update to bind release 9.18.6 Bug Fixes: * When running as a validating resolver forwarding all queries to another resolver, named could crash with an assertion failure. These crashes occurred when the configured forwarder sent a broken DS response and named failed its attempts to find a proper one instead. This has been fixed. * Non-dynamic zones that inherit dnssec-policy from the view or options blocks were not marked as inline-signed and therefore never scheduled to be re-signed. This has been fixed. * The old max-zone-ttl zone option was meant to be superseded by the max-zone-ttl option in dnssec-policy; however, the latter option was not fully effective. This has been corrected: zones no longer load if they contain TTLs greater than the limit configured in dnssec-policy. For zones with both the old max-zone-ttl option and dnssec-policy configured, the old option is ignored, and a warning is generated. * rndc dumpdb -expired was fixed to include expired RRsets, even if stale-cache-enable is set to no and the cache-cleaning time window has passed.

This also applies to the "dump-file" and the "statistics-file". This is solved by having systemd-tmpfiles create a subdirectory "/var/log/named" owned by named:named and changing the file paths accordingly: /var/log/named_querylog -> /var/log/named/querylog /var/log/named_dump.db -> /var/log/named/dump.db /var/log/named.stats -> /var/log/named/stats Also, in "named.service", the ReadWritePath was changed to include "/var/log/named" rather than just "var/log".

[bind-9.18.5.tar.xz bind-9.18.5.tar.xz.sha512.asc] * Wed Jun 15 2022 Josef Möllers <josef.moellers@suse.com> - Upgrade to 9.18.4: Bugs fixed: * Only write key files if the dnssec-policy keymgr has changed the metadata. * When the fetches-per-server quota was adjusted because of an authoritative server timing out more or less frequently, it was incorrectly set to 1 rather than the intended value. Notable functional changes: * Key timing options for `dnssec-keygen` and `dnssec-settime` now accept times as printed by `dnssec-settime -p`. * Key timing options for `dnssec-settime` and related utilities now accept "UNSET" times as printed by `dnssec-settime -p`. This obsoletes the following patch: bind-prevent-buffer-overflow.patch [bind-9.18.4.tar.xz, bind-9.18.4.tar.xz.sha512.asc, bind-prevent-buffer-overflow.patch] * Thu May 19 2022 Josef Möllers <josef.moellers@suse.com> - Upgrade to 9.18.3: Bugs fixed: * Fix a crash in DNS-over-HTTPS (DoH) code caused by premature TLS stream socket object deletion. * RPZ NSIP and NSDNAME rule processing didn't handle stub and static-stub zones at or above the query name. This has now been addressed. * Fixed a deadlock that could occur if an rndc connection arrived during the shutdown of network interfaces. * Refactor the fctx_done() function to set fctx to NULL after detaching, so that reference counting errors will be easier to avoid. * udp_recv() in dispatch could trigger an INSIST when the callback's result indicated success but the response was canceled in the meantime. * Work around a jemalloc quirk which could trigger an out-of-memory condition in named over time. * If there was a pending negative cache DS entry, validations depending upon it could fail. * dig returned a 0 exit status on UDP connection failure. * Fix an assertion failure when using dig with +nssearch and +tcp options by starting the next query in the send_done() callback (like in the UDP mode) instead of doing that recursively in start_tcp(). Also ensure that queries interrupted while connecting are detached properly. * Don't remove CDS/CDNSKEY DELETE records on zone sign when using 'auto-dnssec maintain;'.

So these scripts failed. Some installations still have "createNamedConfInclude" in the NAMED_INITIALIZE_SCRIPTS in /etc/sysconfig/named. The named.prep will now report this but continue. [bsc#1199044, vendor-files.tar.bz2] * Mon Apr 25 2022 Josef Möllers <josef.moellers@suse.com> - Upgrade to 9.18.2: Most important bugs fixed: * The "starting maxtime timer" message related to outgoing zone transfers was incorrectly logged at the ERROR level instead of DEBUG(1). * Ensure that zone maintenance queries have a retry limit. * When using both the `+qr` and `+y` options `dig` could crash if the connection to the first server was not successful. * dig could hang in some cases involving multiple servers in a lookup, when a request fails and the next one refuses to start for some reason, for example if it was an IPv4 mapped IPv6 address. * dig +nssearch was hanging until manually interrupted. * When an UPDATE targets a zone that is not configured, the requested zone name is now logged in the "not authoritative" error message, so that it is easier to track down problematic update clients. * Quote the dns64 prefix in error messages that complain about problems with it, to avoid confusion with the following dns64 ACLs. * When encountering socket error while trying to initiate a TCP connection to a server, dig could hang indefinitely, when there were more servers to try. * When timing-out or having other types of socket errors during a query, dig wasn't trying to perform the lookup using other servers, in case they exist. * Resending a UDP request in the result of a timeout could cause an assertion failure when the resent query's result was SERVFAIL. * Replace single TCP write timer with per-TCP write timers. * Invalid dnssec-policy definitions were being accepted where the defined keys did not cover both KSK and ZSK roles for a given algorithm. This is now checked for and the dnssec-policy is rejected if both roles are not present for all algorithms in use. * Fix query context management issues in the TCP part of dig. Noteworthy functional changes: * Add new "reuseport" option to enable/disable load balancing of sockets. * Set the minimum MTU on UDPv6 and TCPv6 sockets and limit TCP maximum segment size (TCP_MAXSEG) to (1220) for both TCPv4 and TCPv6 sockets.

[CVE-2021-25220] * TCP connection slots may be consumed for an indefinite time frame via a specifically crafted TCP stream sent from a client. This issue can only be triggered on BIND servers which have keep-response-order enabled, which is not the default configuration. The keep-response-order option is an ACL block, and as such, any hosts specified within it will be able to trigger this issue on affected versions. [CVE-2022-0396] * The RFC 8198 Aggressive Use of DNSSEC-Validated Cache feature (synth-from-dnssec) had been refactored and the default has been changed so that is now automatically enabled for dnssec-validating resolvers. Subsequently it was found that repeated patterns of specific queries to servers with this feature enabled could cause an INSIST failure in query.c:query_dname which causes named to terminate unexpectedly. The vulnerability affects BIND resolvers running 9.18.0 that have both dnssec-validation and synth-from-dnssec enabled. (Note that dnssec-validation auto; is the default setting unless configured otherwise in named.conf and that enabling dnssec-validation automatically enables synth-from-dnssec unless explicitly disabled) [CVE-2022-0635] * The refactoring of the recursive client code introduced a "backstop lifetime timer." While BIND is processing a request for a DS record that needs to be forwarded, it waits until this processing is complete or until the backstop lifetime timer has timed out. When the resume_dslookup() function is called as a result of such a timeout, the function does not test whether the fetch has previously been shut down. This introduces the possibility of triggering an assertion failure, which could cause the BIND process to terminate.

This has many enhnancements, bug fixes and changes. The spec file also has mechanisms to run the integrated test suite. MAJOR CHANGES: * Support for securing DNS traffic using Transport Layer Security (TLS). TLS is used by both DNS-over-TLS (DoT) and DNS-over-HTTPS (DoH). * Support for zone transfers over TLS (XFR-over-TLS, XoT) for both incoming and outgoing zone transfers. * The dig tool is now able to send DoT queries (+tls option). * Support for OpenSSL 3.0 APIs was added. A number of utilities have been removed: dnssec-checkds, dnssec-coverage, dnssec-keymgr, which have been deprecated in favor of dnssec-policy feature, as well as python support (package python3-bind). A number of utilities have been moved from (/usr)/sbin to (/usr)/bin The DLZ modules have been put into seperate sub-packages to keep unwanted dependencies out of the main package: * bind-modules-perl: dlz_perl_driver.so * bind-modules-mysql: dlz_mysql_dynamic.so, dlz_mysqldyn_mod.so * bind-modules-ldap: dlz_ldap_dynamic.so * bind-modules-bdbhpt: dlz_bdbhpt_dynamic.so * bind-modules-sqlite3: dlz_sqlite3_dynamic.so * bind-modules-generic: dlz_filesystem_dynamic.so, dlz_wildcard_dynamic.so For a complete list of changes, see * Bind Release Notes https://downloads.isc.org/isc/bind9/9.18.0/doc/arm/html/notes.html * The CHANGES file in the source RPM [bind.spec, bind-9.18.0.tar.xz, bind-9.18.0.tar.xz.sha512.asc, bind-avoid-fallthrough-warning-error.patch, bind-contrib-pthread.patch, named-bootconf.diff, bind-define-missing-threads.patch] * Mon Jan 24 2022 Josef Möllers <josef.moellers@suse.com> - Old-style DLZ drivers have been deprecated in favor of DLZ modules. The DLZ drivers configuration option will be removed from the next major BIND 9 release. The option to use the DLZ modules is already available in BIND 9; please see the ARM section on DLZ modules.

Functional change: * Change the message when accepting TCP connection has failed to say "Accepting TCP connection failed" and change the log level for ISC_R_NOTCONNECTED, ISC_R_QUOTA and ISC_R_SOFTQUOTA results codes from ERROR to INFO. [bind-9.16.24.tar.xz] * Fri Dec 03 2021 Josef Möllers <josef.moellers@suse.com> - Upgrade to 9.16.23 Security issues fixed: The "lame-ttl" option is now forcibly set to 0. This effectively disables the lame server cache, as it could previously be abused by an attacker to significantly degrade resolver performance. (CVE-2021-25219) Bugs fixed: In 9.16.21: * When a dynamic zone was made available in another view using the "in-view" statement, running "rndc freeze" always reported an "already frozen" error even though the zone was successfully frozen. * Stale data in the cache could cause named to send non-minimized queries despite QNAME minimization being enabled. * When a DNSSEC-signed zone which only has a single signing key available is migrated to use KASP, that key is now treated as a Combined Signing Key (CSK). * When a member zone was removed from a catalog zone, journal files for the former were not deleted. * named-checkconf failed to detect syntactically invalid values of the "key" and "tls" parameters used to define members of remote server lists. * Fixed a regression which caused the EDNS TCP Keepalive option to be ignored inadvertently in client requests. It has now been fixed and this option is handled properly again. * Fixed a regression which altered the internal memory structure of zone databases, but neglected to update the MAPAPI value for zone files in "map" format. This caused named to attempt to load incompatible map files, triggering an assertion failure on startup. The MAPAPI value has now been updated, so named rejects outdated files when encountering them. * The thread-local isc_tid_v variable was not properly initialized when running BIND 9 as a Windows Service, leading to a crash on startup. * "map" files exceeding 2GB in size failed to load due to a size comparison that incorrectly treated the file size as a signed integer. In 9.16.22: * Remove the "adjust interface" mechanism which was responsible for setting up listeners on interfaces when the "*-source(-v6)" address and port were the same as the "listen-on(-v6)" address and port. Such a configuration is no longer supported; under certain timing conditions, that mechanism could prevent named from listening on some TCP ports. This has been fixed. * Multiple library names were mistakenly passed to the krb5-config utility when ./configure was invoked with the --with-gssapi=[/path/to/]krb5-config option. This has been fixed by invoking krb5-config separately for each required library. * Fixed a regression which broke backward compatibility for the "check-names master ..." and "check-names slave ..." options. This has been fixed. * Address a potential deadlock when checking zone content consistency. In 9.16.23: * Address Coverity warning in lib/dns/dnssec.c. * Fix a bug when comparing two RSA keys. There was a typo which caused the "p" prime factors to not being compared. * Fix an assertion failure caused by missing member zones during a reload of a catalog zone. This obsoletes bind-CVE-2021-25219.patch and bind-fix-build-with-older-sphinx.patch Other issues: A compile time waring about fall through in a switch statement has been averted by marking the cases as FALLTHROUGH.

[bind.spec] * Thu Nov 04 2021 Josef Möllers <josef.moellers@suse.com> - Fixed CVE-2021-25219: The lame-ttl option controls how long named caches certain types of broken responses from authoritative servers (see the security advisory for details). This caching mechanism could be abused by an attacker to significantly degrade resolver performance. The vulnerability has been mitigated by changing the default value of lame-ttl to 0 and overriding any explicitly set value with 0, effectively disabling this mechanism altogether. ISC's testing has determined that doing that has a negligible impact on resolver performance while also preventing abuse. Administrators may observe more traffic towards servers issuing certain types of broken responses than in previous BIND 9 releases.

[bsc#1190884, vendor-files/config/named.conf, bind.spec] * Thu Aug 19 2021 Josef Möllers <josef.moellers@suse.com> - Upgrade to 9.16.20 Bugs fixed: * An assertion failure occurred when named attempted to send a UDP packet that exceeded the MTU size, if Response Rate Limiting (RRL) was enabled. (CVE-2021-25218) * Zones using KASP and inline-signed zones failed to apply changes from the unsigned zone to the signed zone under certain circumstances. * "rndc reload <zonename>" could trigger a redundant reload for an inline-signed zone whose zone file was not modified since the last "rndc reload". * named failed to check the opcode of responses when performing zone refreshes, stub zone updates, and UPDATE forwarding. * Some changes to "zone-statistics" settings were not properly processed by "rndc reconfig". * The "check DS" code failed to release all resources upon named shutdown when a refresh was in progress. * Authentication of rndc messages could fail if a "controls" statement was configured with multiple key algorithms for the same listener. More changes see CHANGES in the source package. [bsc#1189460, CVE-2021-25218] * Thu Jul 29 2021 Paolo Stivanin <info@paolostivanin.com> - Update to 9.16.19 * A race condition could occur where two threads were competing for the same set of key file locks, leading to a deadlock. This has been fixed. [GL #2786] * create_keydata() created an invalid placeholder keydata record upon a refresh failure, which prevented the database of managed keys from subsequently being read back. This has been fixed. [GL #2686] * KASP support was extended with the "check DS" feature. Zones with "dnssec-policy" and "parental-agents" configured now check for DS presence and can perform automatic KSK rollovers. [GL #1126] * Rescheduling a setnsec3param() task when a zone failed to load on startup caused a hang on shutdown. This has been fixed. [GL #2791] * The configuration-checking code failed to account for the inheritance rules of the "dnssec-policy" option. This has been fixed. [GL #2780] * If nsupdate sends an SOA request and receives a REFUSED response, it now fails over to the next available server. [GL #2758] * For UDP messages larger than the path MTU, named now sends an empty response with the TC (TrunCated) bit set. In addition, setting the DF (Don't Fragment) flag on outgoing UDP sockets was re-enabled. [GL #2790] * Views with recursion disabled are now configured with a default cache size of 2 MB unless "max-cache-size" is explicitly set. This prevents cache RBT hash tables from being needlessly preallocated for such views. [GL #2777] * Change 5644 inadvertently introduced a deadlock: when locking the key file mutex for each zone structure in a different view, the "in-view" logic was not considered. This has been fixed. [GL #2783] * Increasing "max-cache-size" for a running named instance (using "rndc reconfig") did not cause the hash tables used by cache databases to be grown accordingly. This has been fixed. [GL #2770] * Signed, insecure delegation responses prepared by named either lacked the necessary NSEC records or contained duplicate NSEC records when both wildcard expansion and CNAME chaining were required to prepare the response. This has been fixed. [GL #2759] * A bug that caused the NSEC3 salt to be changed on every restart for zones using KASP has been fixed. [GL #2725] * Wed Jul 21 2021 Josef Möllers <josef.moellers@suse.com> - Since BIND 9.9, it has been easier to use tsig-keygen and ddns-confgen to generare TSIG keys. In 9.13, TSIG support was removed from dnssec-keygen, so now it is just for DNSKEY (and KEY for obscure cases). tsig-keygen is now used to generate DDNS keys.

After the DNSSEC records have been removed from the zone, the dnssec-policy can be set to none or removed from the configuration. Setting the dnssec-policy to insecure causes CDS and CDNSKEY DELETE records to be published. [GL #2645] + The implementation of the ZONEMD RR type has been updated to match RFC 8976. [GL #2658] + The draft-vandijk-dnsop-nsec-ttl IETF draft was implemented: NSEC(3) TTL values are now set to the minimum of the SOA MINIMUM value or the SOA TTL. [GL #2347] * Bug Fixes + It was possible for corrupt journal files generated by an earlier version of named to cause problems after an upgrade. This has been fixed. [GL #2670] + TTL values in cache dumps were reported incorrectly when stale-cache-enable was set to yes. This has been fixed. [GL #389] [GL #2289] + A deadlock could occur when multiple rndc addzone, rndc delzone, and/or rndc modzone commands were invoked simultaneously for different zones. This has been fixed. [GL #2626] + named and named-checkconf did not report an error when multiple zones with the dnssec-policy option set were using the same zone file. This has been fixed. [GL #2603] + If dnssec-policy was active and a private key file was temporarily offline during a rekey event, named could incorrectly introduce replacement keys and break a signed zone. This has been fixed. [GL #2596] + When generating zone signing keys, KASP now also checks for key ID conflicts among newly created keys, rather than just between new and existing ones. [GL #2628] * Tue May 18 2021 Josef Möllers <josef.moellers@suse.com> - In /usr/libexec/bind/named.prep the order of arguments for "ln -s" was wrong. [vendor-files/system/named.prep, bsc#1186057] * Mon May 17 2021 Josef Möllers <josef.moellers@suse.com> - "systemctl reload named" does not work: * the "kill" command is in /usr/bin, not in /sbin, * the order of the options/arguments was wrong, and * the "-p" option is wrong (it's not like strace's "-p"). [bsc#1186046, vendor-files/system/named.service] * Mon May 10 2021 Ferdinand Thiessen <rpm@fthiessen.de> - SPEC file: Fixed outdated URL and use secured SourceURLs * Mon May 03 2021 Josef Möllers <josef.moellers@suse.com> - Upgrade to bind 9.16.15 Major changes: * A specially crafted GSS-TSIG query could cause a buffer overflow in the ISC implementation of SPNEGO. (CVE-2021-25216) * named crashed when a DNAME record placed in the ANSWER section during DNAME chasing turned out to be the final answer to a client query. (CVE-2021-25215) * Insufficient IXFR checks could result in named serving a zone without an SOA record at the apex, leading to a RUNTIME_CHECK assertion failure when the zone was subsequently refreshed. This has been fixed by adding an owner name check for all SOA records which are included in a zone transfer. (CVE-2021-25214) More changes see CHANGES in the source package. [bsc#1185345,CVE-2021-25214,CVE-2021-25215,CVE-2021-25216] * Thu Apr 08 2021 Josef Möllers <josef.moellers@suse.com> - Rewrite of named service handling to better cope with systemd protection (see change from Thu Jan 21) by introducing a separate script "named.prep" which runs without restrictions prior to starting named. Removed all references to "lwresd" as "The lightweight resolver daemon and library (lwresd and liblwres) have been removed." (See CHANGES, item 4707) [bind.spec, vendor-files.tar.bz2] * Tue Mar 23 2021 Jan Engelhardt <jengelh@inai.de> - Modernize specfile, and declare /bin/bash as required buildshell (use of {a,b} style expansion). * Fri Mar 12 2021 Matthias Gerstner <matthias.gerstner@suse.com> - pass PIE compiler and linker flags via environment variables to make /usr/bin/delv in bind-tools also position independent (bsc#1183453). - drop pie_compile.diff: no longer needed, this patch is difficult to maintain, the environment variable approach is less error prone. * Thu Feb 18 2021 Josef Möllers <josef.moellers@suse.com> - *** MAJOR CHANGES *** * The libraries shipped with bind are now named after the bind version (eg libisc-9.16.10.so), not some kind of artificial number (eg libisc.so.1608)! * For the time being (ie until the next upgrade), new BIND option "stale-answer-client-timeout" will be disabled (in /etc/named.conf): "stale-answer-enable no;" * All libraries are now in bind-utils as they are used by bind and bind-utils only and bind requires bind-utils. This affects libdns, libirs, libisc, libisccc, libisccfg, libns * Dropped the devel packages as the libraries are used internally only. * Update to 9.16.12 Bugs fixed: - KASP incorrectly set signature validity to the value of the DNSKEY signature validity. - Fix off-by-one bug in ISC SPNEGO implementation. (CVE-2020-8625) - Dig now reports unknown dash options while pre-parsing the options. This prevents "-multi" instead of "+multi" from reporting memory usage before ending option parsing with "Invalid option: -lti". - Fixed a crash in "dnssec-keyfromlabel" when using ECDSA keys. - Emit useful error message when "rndc retransfer" is applied to a zone of inappropriate type. - Improve performance of the DNSSEC verification code by reducing the number of repeated calls to dns_dnssec_keyfromrdata(). - named failed to start when its configuration included a zone with a non-builtin "allow-update" ACL attached. - Address potential double free in generatexml(). - When migrating to KASP, BIND 9 considered keys with the "Inactive" and/or "Delete" timing metadata to be possible active keys. - Fix the "three is a crowd" key rollover bug in KASP by correctly implementing Equation (2) of the "Flexible and Robust Key Rollover" paper. * dnssec-keygen can no longer generate HMAC keys. Use tsig-keygen instead. genDDNSkey script was modified to reflect this. [vendor-files/tools/bind.genDDNSkey, bsc#1180933, CVE-2020-8625, bsc#1182246, bsc#1182483] * Thu Jan 21 2021 Josef Möllers <josef.moellers@suse.com> - Upgrade to version 9.16.11 * Bug fixing (please check CHANGES file in the source RPM) * Functional change: policy none;", named now permits a safe transition to insecure mode and publishes the CDS and CDNSKEY DELETE records, as described in RFC 8078. Remove useless Makefiles and Makefile skeleton files in /usr/share/doc/packages/bind/contrib/ [bind.spec, bsc#1179040] * ** MAJOR CHANGE *** Changed protection of/against "named" from chroot jail to systemd protection. This obsoletes subpackage named-chrootenv. Kudos to Matthias Gerstner <matthias.gerstner@suse.com> [bind.spec, bind-chrootenv.conf, vendor-files.tar.bz2, bsc#1180294]
