Mandriva Linux Security Advisory : ffmpeg (MDVSA-2011:061)
critical Nessus Plugin ID 53273
Language:
Synopsis
The remote Mandriva Linux host is missing one or more security updates.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 vulnerabilities originally discovered by Google Chrome developers were also fixed with this advisory.
The updated packages have been patched to correct these issues.
