OSS-Fuzz is a large-scale fuzz testing platform developed by Google to improve the security and reliability of widely used open source software. Fuzz testing is a proven method for uncovering programming errors such as buffer overflows and memory leaks, which can lead to severe security vulnerabilities. By leveraging guided in-process fuzzing, Google has already identified thousands of issues in projects like Chrome, and this initiative extends the same capabilities to the broader open source community. OSS-Fuzz integrates modern fuzzing engines with sanitizers and runs them at scale in a distributed environment, providing automated testing and continuous monitoring. The platform supports multiple programming languages including C/C++, Rust, Go, Python, Java/JVM, and JavaScript, ensuring wide coverage across critical open source projects.
