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.

- updated to 4.03c
  - Building now gives a build summary what succeeded and what not
  - afl-fuzz:
    - added AFL_NO_STARTUP_CALIBRATION to start fuzzing at once instead
      of calibrating all initial seeds first. Good for large queues
      and long execution times, especially in CIs.
    - default calibration cycles set to 7 from 8, and only add 5 cycles
      to variables queue items instead of 12.
  - afl-cc:
    - fixed off-by-one bug in our pcguard implemenation, thanks for
      @tokatoka for reporting
    - fix for llvm 15 and reenabling LTO, thanks to nikic for the PR!
    - better handling of -fsanitize=..,...,.. lists
    - support added for LLVMFuzzerRunDriver()
    - fix gcc_mode cmplog
    - obtain the map size of a target with setting AFL_DUMP_MAP_SIZE=1
      note that this will exit the target before main()
  - qemu_mode:
    - added AFL_QEMU_TRACK_UNSTABLE to log the addresses of unstable
      edges (together with AFL_DEBUG=1 afl-fuzz). thanks to
      worksbutnottested!
  - afl-analyze broke at some point, fix by CodeLogicError, thank you!
  - afl-cmin/afl-cmin.bash now have an -A option to allow also crashing
    and timeout inputs
  - unicorn_mode:
    - updated upstream unicorn version
    - fixed builds for aarch64
    - build now uses all available cores (forwarded request 1005008 from msmeissn)
