Yesterday we announced that our security advisory feed was being now published following the OSV schema. This was a herculean job by Dan Luhring and Carlos.

One week later the bug count is now at 25 bugs total (github.com/google/oss-fuz…) There's still many improvements to be made to improve success rate of generated targets, but we now have the problem of too many crashes to triage. Automating this will a focus of our future research.

OSV support announced in the latest Ubuntu 24.10 release! This year has seen OSV adoption from many Linux distributions, and the OSV.dev database is starting to become a really comprehensive source of accurate vuln info across major open source ecosystems!

CVE-2024-9143 (openssl-library.org/news/secadv/20…) was disclosed recently, which was found by OSS-Fuzz-Gen! This is a pretty proud example of our team showing the promise of leveraging LLMs enable more fuzzing coverage.

Red Hat joins OSV! openssf.org/blog/2024/11/0… Combined with Ubuntu, Chainguard, and SUSE adopting OSV this year, OSV.dev has really started to become a comprehensive vulnerability source for not only language packages, but also Linux distros!

The OSS-Fuzz team at GoogleĀ is using AI-powered fuzzing to find vulns in open-source software and recently reported 26 new vulns to open-source project maintainers, including one in the OpenSSL library which is critical to most internet infrastructure. security.googleblog.com/2024/11/leveli…

New blog post about OSS-Fuzz AI-powered fuzzing is live! We talk about what went into making LLMs work well enough for this use case to find 26 new vulnerabilities (including a CVE in OpenSSL), as well as what else we have planned to make this better. security.googleblog.com/2024/11/leveli…
