"Multiple vulnerabilities has been identified and fixed in ffmpeg :

oggparsevorbis.c in FFmpeg 0.5 does not properly perform certain
pointer arithmetic, which might allow remote attackers to obtain
sensitive memory contents and cause a denial of service via a crafted
file that triggers an out-of-bounds read. (CVE-2009-4632)

vorbis_dec.c in FFmpeg 0.5 uses an assignment operator when a
comparison operator was intended, which might allow remote attackers
to cause a denial of service and possibly execute arbitrary code via a
crafted file that modifies a loop counter and triggers a heap-based
buffer overflow. (CVE-2009-4633)

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)

FFmpeg 0.5 allows remote attackers to cause a denial of service (hang)
via a crafted file that triggers an infinite loop. (CVE-2009-4636)

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)

Array index error in vorbis_dec.c in FFmpeg 0.5 allows remote
attackers to cause a denial of service and possibly execute arbitrary
code via a crafted Vorbis file that triggers an out-of-bounds read.
(CVE-2009-4640)

flicvideo.c in libavcodec 0.6 and earlier in FFmpeg, as used in
MPlayer and other products, allows remote attackers to execute
arbitrary code via a crafted flic file, related to an arbitrary offset
dereference vulnerability. (CVE-2010-3429)

Fix memory corruption in WMV parsing (CVE-2010-3908)

libavcodec/vorbis_dec.c in the Vorbis decoder in FFmpeg 0.6.1 and
earlier allows remote attackers to cause a denial of service
(application crash) via a crafted .ogg file, related to the
vorbis_floor0_decode function. (CVE-2010-4704)

Multiple buffer overflows in vorbis_dec.c in the Vorbis decoder in
FFmpeg, as used in Google Chrome before 8.0.552.237 and Chrome OS
before 8.0.552.344, allow remote attackers to cause a denial of
service (memory corruption and application crash) or possibly have
unspecified other impact via a crafted WebM file, related to buffers
for (1) the channel floor and (2) the channel residue. (CVE-2011-0480)

Fix heap corruption crashes (CVE-2011-0722)

Fix invalid reads in VC-1 decoding (CVE-2011-0723)

And several additional vulnerabilities originally discovered by Google
Chrome developers were also fixed with this advisory.

The updated packages have been patched to correct these issues."
