# oss-fuzz oss-fuzz is an effort to apply coverage-guided software fuzzing on scale to test open source software. It grew out of Chrome in-process fuzzing effort ([Blog Post](https://security.googleblog.com/2016/08/guided-in-process-fuzzing-of-chrome.html), [Project Page](https://chromium.googlesource.com/chromium/src/testing/libfuzzer/)). *Project Status*: The project currently is in early stage. We focus on libFuzzer first. Documentation and smoothing the process is our main priority. [Open new issue](https://github.com/google/oss-fuzz/issues/new) for questions or feedback. ## Documentation * [New Library Guide](docs/new_library.md) walks through steps necessary to add fuzzers to an open source project. * [Running and Building Fuzzers](docs/building_running_fuzzers.md) documents the process for fuzzers that are *part of target project* source code repository. * [Running and Building External Fuzzers](docs/building_running_fuzzers_external.md) documents the process for fuzzers that are *part of oss-fuzz* source code repository. * [Project List](docs/projects.md) lists OSS projects integrated with oss-fuzz. * [Chrome's Efficient Fuzzer Guide](https://chromium.googlesource.com/chromium/src/testing/libfuzzer/+/HEAD/efficient_fuzzer.md) while contains some chrome-specifics, is an excellent documentation on making your fuzzer better. * [Life of a bug](docs/life_of_a_bug.md) ## Build status [Build status](https://oss-fuzz-build-logs.storage.googleapis.com/status.html) ## Bounties * freetype2: [9](https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=9&can=1&q=&colspec=ID%20Type%20Component%20Status%20Priority%20Milestone%20Owner%20Summary), [10](https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=10&can=1&q=&colspec=ID%20Type%20Component%20Status%20Priority%20Milestone%20Owner%20Summary), [36](https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=36&can=1&q=&colspec=ID%20Type%20Component%20Status%20Priority%20Milestone%20Owner%20Summary) ## References * [libFuzzer](http://llvm.org/docs/LibFuzzer.html) * [Chromium In-Process Fuzzing Project Page](https://chromium.googlesource.com/chromium/src/testing/libfuzzer/)
