OSS-Fuzz

Google's free continuous fuzzing service for critical open-source projects.

Definition

OSS-Fuzz runs libFuzzer, AFL++ and other engines with sanitizers at scale, reports bugs privately to maintainers and discloses them after a deadline. It has found tens of thousands of bugs in open-source software.

Example

A compression library integrates with OSS-Fuzz and receives private crash reports with reproducers.

Exam tip

Example of fuzzing as a supply chain hardening practice.
