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.
