Google has announced the availability of ClusterFuzzLite, a continuous fuzzing open source solution that runs as part of CI/CD workflows to find vulnerabilities faster than ever before. ClusterFuzzLite is a continuous fuzzing solution that runs as part of Continuous Integration (CI) workflows to find vulnerabilities faster than ever before. With just a few lines of code, GitHub users can integrate ClusterFuzzLite into their workflow and fuzz pull requests to catch bugs before they are committed.
Since its release in 2016, over 500 critical open source projects have integrated into Google’s OSS-Fuzz program, resulting in over 6,500 vulnerabilities and 21,000 functional bugs being fixed. ClusterFuzzLite goes hand-in-hand with OSS-Fuzz, by catching regression bugs much earlier in the development process. ClusterFuzzLite currently supports GitHub Actions, Google Cloud Build and Prow.
Large projects including systemd and curl are already using ClusterFuzzLite during code review, with positive results. According to Daniel Stenberg, author of curl, “When the human reviewers nod and have approved the code and your static code analyzers and linters can’t detect any more issues, fuzzing is what takes you to the next level of code maturity and robustness. OSS-Fuzz and ClusterFuzzLite help us maintain curl as a quality project, around the clock, every day and every commit.”
With the release of ClusterFuzzLite, any project can integrate this essential testing standard and benefit from fuzzing. ClusterFuzzLite offers many of the same features as ClusterFuzz, such as continuous fuzzing, sanitizer support, corpus management, and coverage report generation. Most importantly, it’s easy to set up and works with closed source projects, making ClusterFuzzLite a convenient option for any developer who wants to fuzz their software.
