CVE-2013-2495 (opens in a new tab)Amendment
The Ubuntu security team deemed this advisory irrelevant for Ubuntu:13.04.
NVD Description
Note: Versions mentioned in the description apply only to the upstream libav package and not the libav package as distributed by Ubuntu.
The iff_read_header function in iff.c in libavformat in FFmpeg through 1.1.3 does not properly handle data sizes for Interchange File Format (IFF) data during operations involving a CMAP chunk or a video codec, which allows remote attackers to cause a denial of service (integer overflow, out-of-bounds array access, and application crash) or possibly have unspecified other impact via a crafted header.
