honggfuzz
Description
A security oriented, feedback-driven, evolutionary, easy-to-use fuzzer with interesting analysis options. See USAGE for details
- Easy-to-use, just provide it with input corpus (can consist of a single file) and it will work to expand it using feedback-based coverage metrics
- Has a nice track record of uncovered security bugs: e.g. the only vulnerability in OpenSSL with the critical score mark had been discovered by honggfuzz
- Supports several hardware-based (CPU: branch/instruction counting, Intel BTS, Intel PT) and software-based feedback-driven fuzzing methods
- It works (at least) under GNU/Linux, FreeBSD, Mac OS X, Windows/CygWin and Android
- Supports persistent modes of fuzzing (long-lived process calling a fuzzed API repeatedly) with libhfuzz/libhfuzz.a. More on that here
- Can fuzz remote/standalone long-lasting processes (e.g. network servers like Apache's httpd and ISC's bind)
Code
- Latest stable version: 0.9, but you're encouraged to use the master branch

Requirements
- Linux - The BFD library (libbfd-dev) and libunwind (libunwind-dev/libunwind8-dev)
- FreeBSD - gmake, clang-3.6 or newer
- Android - Android SDK/NDK. Also see this detailed doc on how to build and run it
- Windows - CygWin
- Darwin/OS X - Xcode 10.8+
- if Clang/LLVM is used - the BlocksRuntime Library (libblocksruntime-dev)
Trophies
The tool has been used to find a few interesting security problems in major software packages; Examples:
