Buffer overflow in FFmpeg - CVE-2013-7023

Vulnerability details

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

The ff_combine_frame function in libavcodec/parser.c in FFmpeg before 2.1 does not properly handle certain memory-allocation errors, which allows remote attackers to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact via crafted data.
