543 Vulnerabilities in FFmpeg: Hunting Flaws in the Industry Standard
FFmpeg, the open-source library serving as the de facto standard for audio and video processing in mobile apps, carries approximately 543 registered CVEs that frequently appear in bug bounty programs. A Quokka report on over 150,000 applications found critical third-party CVEs in 11% of Android and 13% of iOS apps, with high-severity issues in 65% of Android applications. The article examines three notable vulnerabilities including PixelSmash (CVE-2026-8461), HTTP chunked overflow (CVE-2016-10190), and an AV1 RTP depacketizer flaw (DFVULN-127), each enabling remote code execution through memory corruption. It provides practical guidance on locating FFmpeg binaries inside APKs, identifying integration patterns, determining versions via strings and NDK timestamps, and extracting build configurations to confirm enabled components. Analysts are shown how to locate protocol handlers that serve as entry points without requiring malicious media files. The material targets reverse engineers experienced with ELF libraries and memory corruption issues.
