Mandriva Linux Security Advisory 2011-061 - 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. 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. 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 bypasses a validation check in vorbis_dec.c and triggers a wraparound of the stack pointer, or 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. 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 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. FFmpeg 0.5 allows remote attackers to cause a denial of service via a crafted file that triggers an infinite loop. The av_rescale_rnd function in the AVI demuxer in FFmpeg 0.5 allows remote attackers to cause a denial of service via a crafted AVI file that triggers a divide-by-zero error. 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. 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. Fix memory corruption in WMV parsing. libavcodec/vorbis_dec.c in the Vorbis decoder in FFmpeg 0.6.1 and earlier allows remote attackers to cause a denial of service via a crafted.ogg file, related to the vorbis_floor0_decode function. 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 or possibly have unspecified other impact via a crafted WebM file, related to buffers for Fix heap corruption crashes. Fix invalid reads in VC-1 decoding. 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.

Mandriva Linux Security Advisory MDVSA-2011:061
http://www.mandriva.com/security/
_______________________________________________________________________
Package : ffmpeg
Date : April 1, 2011
Affected: 2010.0
_______________________________________________________________________
Problem Description:
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 vulnerabilites originally discovered by Google
Chrome developers were also fixed with this advisory.
The updated packages have been patched to correct these issues.
