CVE-2014-9676: Ffmpeg

Medium severity, CVSS 6.8. EPSS: 3.3% chance of exploitation in the next 30 days.

The seg_write_packet function in libavformat/segment.c in ffmpeg 2.1.4 and earlier does not free the correct memory location, which allows remote attackers to cause a denial of service ("invalid memory handler") and possibly execute arbitrary code via a crafted video that triggers a use after free.

Affected products

• Ffmpeg Ffmpeg: up to and including 2.1.4
