| Summary: American fuzzy lop is a security-oriented fuzzer | |
American fuzzy lop is a security-oriented fuzzer that employs a novel type of compile-time instrumentation and genetic algorithms to automatically discover clean, interesting test cases that trigger new internal states in the targeted binary. This substantially improves the functional coverage for the fuzzed code. The compact synthesized corpora produced by the tool are also useful for seeding other, more labor- or resource-intensive testing regimes down the road. Compared to other instrumented fuzzers, afl-fuzz is designed to be practical: it has modest performance overhead, uses a variety of highly effective fuzzing strategies and effort minimization tricks, requires essentially no configuration, and seamlessly handles complex, real-world use cases - say, common image parsing or file compression libraries.

* Mon Jun 10 2024 Marcus Meissner <meissner@suse.com>
- updated to 4.21c
* afl-fuzz
- fixed a regression in afl-fuzz that resulted in a 5-10% performace loss
do a switch from gettimeofday() to clock_gettime() which should be rather
three times faster. The reason for this is unknown.
- new queue selection algorithm based on 2 core years of queue data
analysis. gives a noticable improvement on coverage although the results
seem counterintuitive :-)
- added AFL_DISABLE_REDUNDANT for huge queues
- added `AFL_NO_SYNC` environment variable that does what you think it does
- fix AFL_PERSISTENT_RECORD
- run custom_post_process after standard trimming
- prevent filenames in the queue that have spaces
- minor fix for FAST schedules
- more frequent stats update when syncing (todo: check performance impact)
- now timing of calibration, trimming and syncing is measured seperately,
thanks to @eqv!
- -V timing is now accurately the fuzz time (without syncing), before
long calibration times and syncing could result in now fuzzing being
made when the time was already run out until then, thanks to @eqv!
- fix -n uninstrumented mode when ending fuzzing
- enhanced the ASAN configuration
- make afl-fuzz use less memory with cmplog and fix a memleak
* afl-cc:
- re-enable i386 support that was accidently disabled
- fixes for LTO and outdated afl-gcc mode for i386
- fix COMPCOV split compare for old LLVMs
- disable xml/curl/g_ string transform functions because we do not check
for null pointers ... TODO
- ensure shared memory variables are visible in weird build setups
- compatability to new LLVM 19 changes
* afl-cmin
- work with input files that have a space
* afl-showmap
- fix memory leak on shmem testcase usage (thanks to @ndrewh)
- minor fix to collect coverage -C (thanks to @bet4it)
* Fixed a shmem mmap bug (that rarely came up on MacOS)
* libtokencap: script generate_libtoken_dict.sh added by @a-shvedov
* Mon Apr 15 2024 Marcus Meissner <meissner@suse.com>
- updated to 4.20c
+ A new forkserver communication model is now introduced. afl-fuzz is
backward compatible to old compiled targets if they are not built
for CMPLOG/Redqueen, but new compiled targets will not work with
old afl-fuzz versions!
+ Recompile all targets that are instrumented for CMPLOG/Redqueen!
- AFL++ now supports up to 4 billion coverage edges, up from 6 million.
- New compile option: `make PERFORMANCE=1` - this will enable special
CPU dependent optimizations that make everything more performant - but
the binaries will likely won't work on different platforms. Also
enables a faster hasher if the CPU requirements are met.
- The persistent record feature (see config.h) was expanded to also
support replay, thanks to @quarta-qti !
- afl-fuzz:
- the new deterministic fuzzing feature is now activated by default,
deactivate with -z. Parameters -d and -D are ignored.
- small improvements to CMPLOG/redqueen
- workround for a bug with MOpt -L when used with -M - in the future
we will either remove or rewrite MOpt.
- fix for `-t xxx+` feature
- -e extension option now saves the queue items, crashes, etc. with the
extension too
- fixes for trimmming, correct -V time and reading stats on resume by eqv
thanks a lot!
- afl-cc:
- added collision free caller instrumentation to LTO mode. activate with
`AFL_LLVM_LTO_CALLER=1`. You can set a max depth to go through single
block functions with `AFL_LLVM_LTO_CALLER_DEPTH` (default 0)
- fixes for COMPCOV/LAF and most other modules
- fix for GCC_PLUGIN cmplog that broke on std::strings
- afl-whatsup:
- now also displays current average speed
- small bugfixes
- Fixes for aflpp custom mutator and standalone tool
- Minor edits to afl-persistent-config
- Prevent temporary files being left behind on aborted afl-whatsup
- More CPU benchmarks added to benchmark/
* Mon Feb 05 2024 Marcus Meissner <meissner@suse.com>

- afl-fuzz:
- fixed the new mutation implementation for two bugs
- added `AFL_FINAL_SYNC` which forces a final fuzzer sync (also for `-F`)
before terminating.

speed is in comparison to other setups.
* Fri Aug 11 2023 Marcus Meissner <meissner@suse.com>
- updated to 4.08c
- afl-fuzz:
- new mutation engine: mutations that favor discovery more paths are
prefered until no new finds for 10 minutes then switching to mutations
that favor triggering crashes. Modes and switch time can be configured
with `-P`. Also input mode for the target can be defined with `-a` to
be `text` or `binary` (defaults to `generic`)
- new custom mutator that has the new afl++ engine (so it can easily
incorporated into new custom mutators), and also comes with a standalone
command line tool! See custom_mutators/aflpp/standalone/
- display the state of the fuzzing run in the UI :-)
- fix timeout setting if '+' is used or a session is restarted
- -l X option to enable base64 transformation solving
- allow to disable CMPLOG with '-c -' (e.g. afl.rs enforces '-c 0' on
every instance which is counterproductive).

set -c 0 to tell afl-fuzz that the fuzzing binary is also for
CMPLOG.
- new commandline options -g/G to set min/max length of generated
fuzz inputs
- you can set the time for syncing to other fuzzer now with
AFL_SYNC_TIME

- fix counting favorites (just a display thing)
- afl-cc:
- fix cmplog rtn (rare crash and not being able to gather ptr data)
- fix our own PCGUARD implementation to compile with llvm 10.0.1
- link runtime not to shared libs
- ensure shared libraries are properly built and instrumented
- AFL_LLVM_INSTRUMENT_ALLOW/DENY were not implemented for LTO, added
- show correct LLVM PCGUARD NATIVE mode when auto switching to it
and keep fsanitize-coverage-*list=...
Short mnemnonic NATIVE is now also accepted.
- qemu_mode (thanks @realmadsci):
- move AFL_PRELOAD and AFL_USE_QASAN logic inside afl-qemu-trace
- add AFL_QEMU_CUSTOM_BIN
- unicorn_mode
- accidently removed the subfolder from github, re-added
- added DEFAULT_PERMISSION to config.h for all files created, default
to 0600
* Tue Mar 16 2021 Marcus Meissner <meissner@suse.com>
- updated to 3.11c
- afl-fuzz:
- better auto detection of map size
- fix sanitizer settings (bug since 3.10c)
- fix an off-by-one overwrite in cmplog
- add non-unicode variants from unicode-looking dictionary entries
- Rust custom mutator API improvements
- Imported crash stats painted yellow on resume (only new ones are red)
- afl-cc:
- added AFL_NOOPT that will just pass everything to the normal
gcc/clang compiler without any changes - to pass weird configure
scripts
- fixed a crash that can occur with ASAN + CMPLOG together plus
better support for unicode (thanks to @stbergmann for reporting!)
- fixed a crash in LAF transform for empty strings
- handle erroneous setups in which multiple afl-compiler-rt are
compiled into the target. This now also supports dlopen()
instrumented libs loaded before the forkserver and even after the
forkserver is started (then with collisions though)
- the compiler rt was added also in object building (-c) which
should have been fixed years ago but somewhere got lost :(
- Renamed CTX to CALLER, added correct/real CTX implementation to
CLASSIC
- qemu_mode:
- added AFL_QEMU_EXCLUDE_RANGES env by @realmadsci, thanks!
- if no new/updated checkout is wanted, build with:
NO_CHECKOUT=1 ./build_qemu_support.sh
- we no longer perform a "git drop"
- afl-cmin: support filenames with spaces
- afl-3.0c-fix-paths.patch: refreshed
* Mon Mar 01 2021 Marcus Meissner <meissner@suse.com>
- update to 3.10c
- Mac OS ARM64 support
- Android support fixed and updated by Joey Jiaojg - thanks!
- New selective instrumentation option with __AFL_COVERAGE_* commands
to be placed in the source code.
Check out instrumentation/README.instrument_list.md
- afl-fuzz
- Making AFL_MAP_SIZE (mostly) obsolete - afl-fuzz now learns on
start the target map size
- upgraded cmplog/redqueen: solving for floating point, solving
transformations (e.g. toupper, tolower, to/from hex, xor,
arithmetics, etc.). This is costly hence new command line option
`-l` that sets the intensity (values 1 to 3). Recommended is 2.
- added `AFL_CMPLOG_ONLY_NEW` to not use cmplog on initial seeds
from `-i` or resumes (these have most likely already been done)
- fix crash for very, very fast targets+systems (thanks to mhlakhani
for reporting)
- on restarts (`-i`)/autoresume (AFL_AUTORESUME) the stats are now
reloaded and used, thanks to Vimal Joseph for this patch!
- changed the meaning of '+' of the '-t' option, it now means to
auto-calculate the timeout with the value given being the max
timeout. The original meaning of skipping timeouts instead of
abort is now inherent to the -t option.
- if deterministic mode is active (`-D`, or `-M` without `-d`) then
we sync after every queue entry as this can take very long time
otherwise
- added minimum SYNC_TIME to include/config.h (30 minutes default)
- better detection if a target needs a large shared map
- fix for `-Z`
- fixed a few crashes
- switched to an even faster RNG
- added hghwng's patch for faster trace map analysis
- printing suggestions for mistyped `AFL_` env variables
- added Rust bindings for custom mutators (thanks @julihoh)
- afl-cc
- allow instrumenting LLVMFuzzerTestOneInput
- fixed endless loop for allow/blocklist lines starting with a
comment (thanks to Zherya for reporting)
- cmplog/redqueen now also tracks floating point, _ExtInt() + 128bit
- cmplog/redqueen can now process basic libc++ and libstdc++
std::string comparisons (no position or length type variants)
- added support for __afl_coverage_interesting() for LTO and our
own PCGUARD (llvm 10.0.1+), read more about this function and
selective coverage in instrumentation/README.instrument_list.md
- added AFL_LLVM_INSTRUMENT option NATIVE for native clang pc-guard
support (less performant than our own), GCC for old afl-gcc and
CLANG for old afl-clang
- fixed a potential crash in the LAF feature
- workaround for llvm bitcast lto bug
- workaround for llvm 13
- qemuafl
- QASan (address sanitizer for Qemu) ported to qemuafl!
See qemu_mode/libqasan/README.md
- solved some persistent mode bugs (thanks Dil4rd)
- solved an issue when dumping the memory maps (thanks wizche)
- Android support for QASan
- unicornafl
- Substantial speed gains in python bindings for certain use cases
- Improved rust bindings
- Added a new example harness to compare python, c and rust bindings
- afl-cmin and afl-showmap now support the -f option
- afl_plot now also generates a graph on the discovered edges
- changed default: no memory limit for afl-cmin and afl-cmin.bash
- warn on any _AFL and __AFL env vars.
- set AFL_IGNORE_UNKNOWN_ENVS to not warn on unknown AFL_... env vars
- added dummy Makefile to instrumentation/
- Updated utils/afl_frida to be 5% faster, 7% on x86_x64
- Added `AFL_KILL_SIGNAL` env variable (thanks @v-p-b)
- @Edznux added a nice documentation on how to use rpc.statsd with
afl++ in docs/rpc_statsd.md, thanks!
