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 47)
- updated to 2.61c
- use -march=native if available
- most tools now check for mistyped environment variables
- gcc 10 is now supported
- the memory safety checks are now disabled for a little more speed during
fuzzing (only affects creating queue entries), can be toggled in config.h
- afl-fuzz:
- MOpt out of bounds writing crash fixed
- now prints the real python version support compiled in
- set stronger performance compile options and little tweaks
- Android: prefer bigcores when selecting a CPU
- CmpLog forkserver
- Redqueen input-2-state mutator (cmp instructions only ATM)
- all Python 2+3 versions supported now
- changed execs_per_sec in fuzzer_stats from "current" execs per second
(which is pointless) to total execs per second
- bugfix for dictionary insert stage count (fix via Google repo PR)
- added warning if -M is used together with custom mutators with _ONLY option
- AFL_TMPDIR checks are now later and better explained if they fail
- llvm_mode
- InsTrim: three bug fixes:
1. (minor) no pointless instrumentation of 1 block functions
2. (medium) path bug that leads a few blocks not instrumented that
should be
3. (major) incorrect prev_loc was written, fixed!
- afl-clang-fast:
- show in the help output for which llvm version it was compiled for
- now does not need to be recompiled between trace-pc and pass
instrumentation. compile normally and set AFL_LLVM_USE_TRACE_PC :)
- LLVM 11 is supported (forwarded request 779147 from msmeissn)
