 Mandriva Linux Security Advisory                         MDKSA-2005:232

 Package : gstreamer-ffmpeg
 Date    : December 14, 2005
 Affected: 2006.0
 _______________________________________________________________________
 
 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.
 
 Gstreamer-ffmpeg is built with a private copy of ffmpeg containing
 this same code.
 
 The updated packages have been patched to prevent this problem.
