CVE-2014-8549 (opens in a new tab)Amendment
The Ubuntu security team deemed this advisory irrelevant for Ubuntu:14.04.
NVD Description
Note: Versions mentioned in the description apply only to the upstream libav package and not the libav package as distributed by Ubuntu.
libavcodec/on2avc.c in FFmpeg before 2.4.2 does not constrain the number of channels to at most 2, which allows remote attackers to cause a denial of service (out-of-bounds access) or possibly have unspecified other impact via crafted On2 data.
