OSS-Fuzz: Continuous Fuzzing for Open Source Software
Fuzz testing is a well-known technique for uncovering programming errors in
software. Many of these detectable errors, like buffer overflow, can have
serious security implications. Google has found thousands of security
vulnerabilities and stability bugs by deploying guided in-process fuzzing of
Chrome components, and we now want to share that service with the open source
community.
In cooperation with the Core Infrastructure Initiative and the OpenSSF,
OSS-Fuzz aims to make common open source software more secure and stable by
combining modern fuzzing techniques with scalable, distributed execution.
We support the libFuzzer, AFL++, and Honggfuzz fuzzing engines in
combination with Sanitizers, as well as ClusterFuzz, a distributed fuzzer
execution environment and reporting tool.
Currently, OSS-Fuzz supports C/C++, Rust, Go, Python and Java/JVM code. Other languages
supported by LLVM may work too. OSS-Fuzz supports fuzzing x86_64 and i386
builds.
