CVE-2014-9676

Publication date 28 February 2015

Last updated 24 July 2024

Ubuntu priority

Medium

Why this priority?

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.
