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 50)
- updated to 2.64c
- llvm_mode LTO mode:
- now requires llvm11 - but compiles all targets! :)
- autodictionary feature added, enable with `AFL_LLVM_LTO_AUTODICTIONARY`
- variable map size usage
- afl-fuzz:
- variable map size support added (only LTO mode can use this)
- snapshot feature usage now visible in UI
- Now setting `-L -1` will enable MOpt in parallel to normal mutation.
Additionally, this allows to run dictionaries, radamsa and cmplog.
- fix for cmplog/redqueen mode if stdin was used
- fix for writing a better plot_data file
- qemu_mode: fix for persistent mode (which would not terminate or get stuck)
- compare-transform/AFL_LLVM_LAF_TRANSFORM_COMPARES now transforms also
static global and local variable comparisons (cannot find all though)
- extended forkserver: map_size and more information is communicated to
afl-fuzz (and afl-fuzz acts accordingly)
- new environment variable: AFL_MAP_SIZE to specify the size of the shared map
- if AFL_CC/AFL_CXX is set but empty afl compilers did fail, fixed
(this bug is in vanilla afl too)
- added NO_PYTHON flag to disable python support when building afl-fuzz
- more refactoring (forwarded request 795493 from msmeissn)
