CVE-2014-9603: Ffmpeg

High severity, CVSS 7.5. EPSS: 2% chance of exploitation in the next 30 days.

The vmd_decode function in libavcodec/vmdvideo.c in FFmpeg before 2.5.2 does not validate the relationship between a certain length value and the frame width, which allows remote attackers to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact via crafted Sierra VMD video data.

Affected products

• Ffmpeg Ffmpeg: up to and including 2.5.1
