 Mandriva Linux Security Advisory                         MDKSA-2005:229
 http://www.mandriva.com/security/
 _______________________________________________________________________

 Package : xmovie
 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.

 Xmovie is built with a private copy of ffmpeg containing this 
 same code.

 The updated packages have been patched to prevent this problem.
