-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 _______________________________________________________________________ Mandriva Linux Security Advisory MDVSA-2011:112 http://www.mandriva.com/security/ _______________________________________________________________________ Package : blender Date : July 18, 2011 Affected: 2009.0 _______________________________________________________________________ Problem Description: Multiple vulnerabilities have been identified and fixed in blender: 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) Fix invalid reads in VC-1 decoding (CVE-2011-0723) Packages for 2009.0 are provided as of the Extended Maintenance Program.
