Open Source Software (OSS) is extremely important to Google, and we rely on OSS in a variety of customer-facing and internal projects. We also understand the difficulty and importance of securing the open source ecosystem, and are continuously looking for ways to simplify it.
For the OSS community, we currently provide OSS-Fuzz, a free continuous fuzzing infrastructure hosted on the Google Cloud Platform. OSS-Fuzz uncovers security vulnerabilities and stability issues, and reports them directly to developers. Since launching in December 2016, OSS-Fuzz has reported over 9,000 bugs directly to open source developers.
In addition to OSS-Fuzz, Google’s security team maintains several internal tools for identifying bugs in both Google internal and Open Source code. Until recently, these issues were manually reported to various public bug trackers by our security team and then monitored until they were resolved. Unresolved bugs were eligible for the Patch Rewards Program. While this reporting process had some success, it was overly complex. Now, by unifying and automating our fuzzing tools, we have been able to consolidate our processes into a single workflow, based on OSS-Fuzz. Projects integrated with OSS-Fuzz will benefit from being reviewed by both our internal and external fuzzing tools, thereby increasing code coverage and discovering bugs faster.
We are committed to helping open source projects benefit from integrating with our OSS-Fuzz fuzzing infrastructure. In the coming weeks, we will reach out via email to critical projects that we believe would be a good fit and support the community at large. Projects that integrate are eligible for rewards ranging from $1,000 (initial integration) up to $20,000 (ideal integration); more details are available here. These rewards are intended to help offset the cost and effort required to properly configure fuzzing for OSS projects. If you would like to integrate your project with OSS-Fuzz, please submit your project for review. Our goal is to admit as many OSS projects as possible and ensure that they are continuously fuzzed.
Once contacted, we might provide a sample fuzz target to you for easy integration. Many of these fuzz targets are generated with new technology that understands how library APIs are used appropriately. Watch this space for more details on how Google plans to further automate fuzz target creation, so that even more open source projects can benefit from continuous fuzzing.
Thank you for your continued contributions to the Open Source community. Let’s work together on a more secure and stable future for Open Source Software.
