Problembeschreibung

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.
