Package name ffmpeg
Date December 14th, 2005
Advisory ID MDKSA-2005:231
Affected versions CS3.0, 2006.0
Synopsis Updated ffmpeg packages fix buffer overflow vulnerability

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.
