| kplybon | 8216f27 | 2019-08-08 10:12:25 -0400 | [diff] [blame] | 4 | technique for uncovering programming errors in software. |
| Max Moroz | 40a183b | 2019-08-09 12:35:14 -0700 | [diff] [blame] | 5 | 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), |
| kplybon | d8af01c | 2019-08-09 15:24:43 -0400 | [diff] [blame] | 6 | and we now want to share that service with the open source community. |

| Abhishek Arya | 938735b | 2020-06-12 16:00:38 -0700 | [diff] [blame] | 15 | We support the [libFuzzer](http://llvm.org/docs/LibFuzzer.html), [AFL](https://lcamtuf.coredump.cx/afl/) and |
| 16 | [Honggfuzz](https://github.com/google/honggfuzz) fuzzing engines |
| kplybon | 8216f27 | 2019-08-08 10:12:25 -0400 | [diff] [blame] | 17 | in combination with [Sanitizers](https://github.com/google/sanitizers), as well as |
| 18 | [ClusterFuzz](https://github.com/google/clusterfuzz), |
| 19 | a distributed fuzzer execution environment and reporting tool. |

| jonathanmetzman | 984b792 | 2019-08-19 14:07:33 -0700 | [diff] [blame] | 21 | Currently, OSS-Fuzz supports C/C++, Rust, and Go code. Other languages supported by [LLVM](http://llvm.org) may work too. |
| 22 | OSS-Fuzz supports fuzzing x86_64 and i386 builds. |
