CVE-2014-9676
Published: 28 February 2015
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.
From the Ubuntu Security Team
It was discovered that Libav incorrectly handled certain media files. An attacker could possibly use this issue to cause a denial of service or other unspecified impact.
