Mandriva Linux Security Advisory MDKSA-2005:231
http://www.mandriva.com/security/
__________________________________________________ _____________________

Package : ffmpeg
Date : December 14, 2005
Affected: 2006.0, Corporate 3.0
__________________________________________________ _____________________

Problem Description:

Simon Kilvington discovered a vulnerability in FFmpeg libavcodec,
which can be exploited by malicious people to cause a DoS (Denial
of Service) and potentially to compromise a user's system.

The vulnerability is caused due to a boundary error in the
"avcodec_default_get_buffer()" function of "utils.c" in libavcodec.
This can be exploited to cause a heap-based buffer overflow when a
specially-crafted 1x1 ".png" file containing a palette is read.

The updated packages have been patched to prevent this problem.
