Buffer overflow in FFmpeg - CVE-2013-7011

Vulnerability details

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

The read_header function in libavcodec/ffv1dec.c in FFmpeg before 2.1 does not prevent changes to global parameters, which allows remote attackers to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact via crafted FFV1 data.
