CVE-2013-2495: The iff_read_header function in iff.c in libavformat in FFmpeg through 1.1.3 does not properly handle data...

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.

Security readout for executives and security teams

This is an old FFmpeg parsing flaw in IFF media handling. A maliciously crafted media header could crash software that uses vulnerable FFmpeg/libavformat code, causing denial of service. The public record also says unspecified other impact may be possible, but does not provide confirmed details. Exposure is most likely where older FFmpeg/libavformat, or products embedding it, process untrusted IFF media files. The source bundle does not identify specific downstream products beyond FFmpeg through 1.1.3 and Ubuntu advisory coverage. Treat this as a legacy media-processing denial-of-service risk. Prioritize internet-facing or automated media ingestion systems first, especially where untrusted uploads can reach FFmpeg. Business urgency is lower than confirmed code-execution flaws, but stale embedded FFmpeg copies can persist unnoticed. Mitigation focus: Upgrade FFmpeg/libavformat using vendor-supported packages or fixed upstream builds.; Review Ubuntu USN-1790-1 if managing affected Ubuntu systems.; Inventory applications that bundle FFmpeg rather than using system packages..
