CVE-2013-2276

Publication date 27 February 2013

Last updated 24 July 2024

Ubuntu priority

Low

Why this priority?

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.
