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 31)
- update to 2.39b:
- Improved error reporting in afl-cmin. Suggested by floyd.
- Made a minor tweak to trace-pc-guard support. Suggested by kcc.
- Added a mention of afl-monitor.
- update to 2.38b:
* Added -mllvm -sanitizer-coverage-block-threshold=0 to
trace-pc-guard mode
* Fixed a cosmetic bad free() bug when aborting -S sessions
* Made a small change to afl-whatsup to sort fuzzers by name.
* Fixed a minor issue with malloc(0) in libdislocator
* Changed the clobber pattern in libdislocator to a slightly more
reliable one
* Added a note about THP performance
* Added a somewhat unofficial support for running afl-tmin with a
baseline "mask" that causes it to minimize only for edges that
are unique to the input file, but not to the "boring" baseline.
* "Fixed" a getPassName() problem with never versions of clang.
