CVE-2013-2495

Publication date 9 March 2013

Last updated 24 July 2024

Ubuntu priority

Medium

Why this priority?

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.
