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 58)
- updated to 3.12c
- afl-fuzz:
- added AFL_TARGET_ENV variable to pass extra env vars to the target
(for things like LD_LIBRARY_PATH)
- fix map detection, AFL_MAP_SIZE not needed anymore for most cases
- 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 (forwarded request 881188 from msmeissn)
