The avcodec_decode_audio4 function in utils.c in libavcodec in FFmpeg before 1.1.3 does not verify the decoding state before proceeding with certain skip operations, which allows remote attackers to cause a denial of service (out-of-bounds array access and application crash) or possibly have unspecified other impact via crafted audio data.

Security readout for executives and security teams

CVE-2013-2276 is an old FFmpeg audio decoding flaw. A remote attacker could supply crafted audio that causes an application using vulnerable libavcodec code to crash. Business urgency depends on whether any internet-facing or user-upload media workflow still uses FFmpeg before 1.1.3. Exposure is most likely in legacy applications, appliances, or media pipelines embedding FFmpeg/libavcodec before 1.1.3 and decoding audio from users, partners, or the internet. The source bundle does not provide CPEs, downstream vendor lists, or package names. Treat this as a legacy exposure cleanup item unless vulnerable media decoding is internet-facing or business-critical. Prioritize systems accepting untrusted audio because the confirmed impact is service crash, which can affect availability. Mitigation focus: Upgrade FFmpeg/libavcodec to 1.1.3 or later where applicable.; Check downstream vendor advisories for bundled FFmpeg fixes.; Restrict untrusted audio processing until vulnerable components are replaced..
