Package : mplayer
Date : May 16, 2011
Affected: 2009.0
_______________________________________________________________________

Problem Description:

Multiple vulnerabilities have been identified and fixed in mplayer:

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)

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)

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

Packages for 2009.0 are provided as of the Extended Maintenance
Program. Please visit this link to learn more:
