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 53 (latest revision is 82)
- updated to 2.67c - Support for improved afl++ snapshot module: https://github.com/AFLplusplus/AFL-Snapshot-LKM - Due to the instrumentation needing more memory, the initial memory sizes for -m have been increased - afl-fuzz: - added -F option to allow -M main fuzzers to sync to foreign fuzzers, e.g. honggfuzz or libfuzzer - added -b option to bind to a specific CPU - eliminated CPU affinity race condition for -S/-M runs - expanded havoc mode added, on no cycle finds add extra splicing and MOpt into the mix - fixed a bug in redqueen for strings and made deterministic with -s - llvm_mode: - now supports llvm 12 - support for AFL_LLVM_ALLOWLIST/AFL_LLVM_DENYLIST (previous AFL_LLVM_WHITELIST and AFL_LLVM_INSTRUMENT_FILE are deprecated and are matched to AFL_LLVM_ALLOWLIST). The format is compatible to llvm sancov, and also supports function matching :) - added neverzero counting to trace-pc/pcgard - fixes for laf-intel float splitting (thanks to mark-griffin for reporting) - fixes for llvm 4.0 - skipping ctors and ifuncs for instrumentation - LTO: switch default to the dynamic memory map, set AFL_LLVM_MAP_ADDR for a fixed map address (eg. 0x10000) - LTO: improved stability for persistent mode, no other instrumentation has that advantage - LTO: fixed autodict for long strings - LTO: laf-intel and redqueen/cmplog are now applied at link time (forwarded request 827912 from msmeissn)
