1) Input validation error

EUVDB-ID: #VU43053

Risk: Medium

CVSSv4.0: 2.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2013-2276

Exploit availability: No

Description

The vulnerability allows a remote non-authenticated attacker to read and manipulate data.

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.

Mitigation

Install update from vendor's website.
