CVE-2009-4635: Ffmpeg

High severity, CVSS 9.3. EPSS: 8.1% chance of exploitation in the next 30 days.

FFmpeg 0.5 allows remote attackers to cause a denial of service and possibly execute arbitrary code via a crafted MOV container with improperly ordered tags that cause (1) mov.c and (2) utils.c to use inconsistent codec types and identifiers, leading to processing of a video-structure pointer by the mp3 decoder, and a stack-based buffer overflow.
