High severity, CVSS 7.5. EPSS: 2.5% chance of exploitation in the next 30 days.

libavcodec/utils.c in FFmpeg before 2.4.2 omits a certain codec ID during enforcement of alignment, which allows remote attackers to cause a denial of service (out-of-bounds access) or possibly have unspecified other impact via crafted JV data.

Affected products

• Canonical Ubuntu Linux: version 12.04 only
• Debian Debian Linux: version 8.0 only
• Ffmpeg Ffmpeg: up to and including 2.4.1
