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.

(revision 51)
- updated to 2.65c
- afl-fuzz:
- AFL_MAP_SIZE was not working correctly
- better python detection
- an old, old bug in afl that would show negative stability in rare
circumstances is now hopefully fixed
- AFL_POST_LIBRARY was deprecated, use AFL_CUSTOM_MUTATOR_LIBRARY
instead (see docs/custom_mutators.md)
- llvm_mode:
- afl-clang-fast/lto now do not skip single block functions. This
behaviour can be reactivated with AFL_LLVM_SKIPSINGLEBLOCK
- if LLVM 11 is installed the posix shm_open+mmap is used and a fixed
address for the shared memory map is used as this increases the
fuzzing speed
- InsTrim now has an LTO version! :-) That is the best and fastest mode!
- fixes to LTO mode if instrumented edges > MAP_SIZE
- CTX and NGRAM can now be used together
- CTX and NGRAM are now also supported in CFG/INSTRIM mode
- AFL_LLVM_LAF_TRANSFORM_COMPARES could crash, fixed
- added AFL_LLVM_SKIP_NEVERZERO to skip the never zero coverage counter
implementation. For targets with few or no loops or heavily called
functions. Gives a small performance boost.
- qemu_mode:
- add information on PIE/PIC load addresses for 32 bit
- better dependency checks
- gcc_plugin:
- better dependency checks
- unicorn_mode:
- validate_crash_callback can now count non-crashing inputs as crash as well
- better submodule handling (forwarded request 805785 from msmeissn)
