Twenty One Zero-Days in FFmpeg
Security researchers at depthfirst discovered 21 zero-day vulnerabilities in the FFmpeg media library using an autonomous security agent. The findings include remote code execution primitives and highlight the effectiveness of AI models in auditing complex, legacy C codebases.
Why it matters
Because FFmpeg is a foundational component of global streaming infrastructure, these vulnerabilities pose significant security risks to a vast array of software.
TLDR: depthfirst’s production autonomous security agent discovered 21 zero-day vulnerabilities in FFmpeg, after intensive security analysis by Google and Anthropic. Moving beyond theoretical analysis, our agent produces concrete, reproducible PoC inputs to confirm its findings at a fraction of the costs ($1k vs. $10k). Several of the findings had been sitting latent for 15 to 20 years. We explored the exploitability of the issues and developed a PoC demonstrating a RCE exploit primitive.
