 Mandriva Linux Security Advisory                         MDVSA-2011:059
 http://www.mandriva.com/security/
 _______________________________________________________________________

 Package : ffmpeg
 Date    : April 1, 2011
 Affected: Corporate 4.0
 _______________________________________________________________________

 Problem Description:

 Multiple vulnerabilities has been identified and fixed in ffmpeg:
 
 Multiple integer underflows in FFmpeg 0.5 allow remote attackers to
 cause a denial of service and possibly execute arbitrary code via a
 crafted file that (1) bypasses a validation check in vorbis_dec.c
 and triggers a wraparound of the stack pointer, or (2) access a
 pointer from out-of-bounds memory in mov.c, related to an elst tag
 that appears before a tag that creates a stream. (CVE-2009-4634)
 
 FFmpeg 0.5 allows remote attackers to cause a denial of service and
 possibly execute arbitrary code via a crafted MOV container with
 improperly ordered tags that cause (1) mov.c and (2) utils.c to use
 inconsistent codec types and identifiers, which causes the mp3 decoder
 to process a pointer for a video structure, leading to a stack-based
 buffer overflow. (CVE-2009-4635)
 
 The av_rescale_rnd function in the AVI demuxer in FFmpeg 0.5 allows
 remote attackers to cause a denial of service (crash) via a crafted
 AVI file that triggers a divide-by-zero error. (CVE-2009-4639)
 
 And several additional vulnerabilites originally discovered by Google
 Chrome developers were also fixed with this advisory.
 
 The updated packages have been patched to correct these issues.
