# OSS-Fuzz
|
|
|
|
[Fuzz testing](https://en.wikipedia.org/wiki/Fuzz_testing) is a well-known
|
|
technique for uncovering programming errors in software.
|
|
Many of these detectable errors, like [buffer overflow](https://en.wikipedia.org/wiki/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](https://security.googleblog.com/2016/08/guided-in-process-fuzzing-of-chrome.html),
|
|
and we now want to share that service with the open source community.

|
|
|
|
In cooperation with the [Core Infrastructure Initiative](https://www.coreinfrastructure.org/),
|
|
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](http://llvm.org/docs/LibFuzzer.html) and [AFL](https://lcamtuf.coredump.cx/afl/) fuzzing engines
|
|
in combination with [Sanitizers](https://github.com/google/sanitizers), as well as
|
|
[ClusterFuzz](https://github.com/google/clusterfuzz),
|
|
a distributed fuzzer execution environment and reporting tool.
|
|
|
|
Currently, OSS-Fuzz supports C/C++, Rust, and Go code. Other languages supported by [LLVM](http://llvm.org) may work too.
|
|
OSS-Fuzz supports fuzzing x86_64 and i386 builds.

## Learn more about fuzzing
|
|
|
|
This documentation describes how to use OSS-Fuzz service for your open source project.
|
|
To learn more about fuzzing in general, we recommend reading [libFuzzer tutorial]
|
|
and the other docs in [google/fuzzing] repository. These and some other resources
|
|
are listed on the [useful links]({{ site.baseurl }}/reference/useful-links/#tutorials) page.
