Message-Id: <E1SUGec-0008Sz-Mr@titan.mandriva.com> Date: Tue, 15 May 2012 14:15:01 +0200 From: security@...driva.com To: full-disclosure@...ts.grok.org.uk Subject: [ MDVSA-2012:075 ] ffmpeg -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 _______________________________________________________________________ Mandriva Linux Security Advisory MDVSA-2012:075 http://www.mandriva.com/security/ _______________________________________________________________________ Package : ffmpeg Date : May 15, 2012 Affected: 2010.1 _______________________________________________________________________ Problem Description: Multiple vulnerabilities has been found and corrected in ffmpeg: The Matroska format decoder in FFmpeg does not properly allocate memory, which allows remote attackers to execute arbitrary code via a crafted file (CVE-2011-3362, CVE-2011-3504). cavsdec.c in libavcodec in FFmpeg allows remote attackers to cause a denial of service (incorrect write operation and application crash) via an invalid bitstream in a Chinese AVS video (aka CAVS) file, related to the decode_residual_block, check_for_slice, and cavs_decode_frame functions, a different vulnerability than CVE-2011-3362 (CVE-2011-3973). Integer signedness error in the decode_residual_inter function in cavsdec.c in libavcodec in FFmpeg allows remote attackers to cause a denial of service (incorrect write operation and application crash) via an invalid bitstream in a Chinese AVS video (aka CAVS) file, a different vulnerability than CVE-2011-3362 (CVE-2011-3974). Double free vulnerability in the Theora decoder in FFmpeg allows remote attackers to cause a denial of service or possibly have unspecified other impact via a crafted stream (CVE-2011-3892). FFmpeg does not properly implement the MKV and Vorbis media handlers, which allows remote attackers to cause a denial of service (out-of-bounds read) via unspecified vectors (CVE-2011-3893). Heap-based buffer overflow in the Vorbis decoder in FFmpeg allows remote attackers to cause a denial of service or possibly have unspecified other impact via a crafted stream (CVE-2011-3895). An error within the QDM2 decoder (libavcodec/qdm2.c) can be exploited to cause a buffer overflow (CVE-2011-4351). An integer overflow error within the "vp3_dequant()" function (libavcodec/vp3.c) can be exploited to cause a buffer overflow (CVE-2011-4352). Errors within the "av_image_fill_pointers()", the "vp5_parse_coeff()", and the "vp6_parse_coeff()" functions can be exploited to trigger out-of-bounds reads (CVE-2011-4353). It was discovered that Libav incorrectly handled certain malformed VMD files. If a user were tricked into opening a crafted VMD file, an attacker could cause a denial of service via application crash, or possibly execute arbitrary code with the privileges of the user invoking the program (CVE-2011-4364). It was discovered that Libav incorrectly handled certain malformed SVQ1 streams. If a user were tricked into opening a crafted SVQ1 stream file, an attacker could cause a denial of service via application crash, or possibly execute arbitrary code with the privileges of the user invoking the program (CVE-2011-4579). The updated packages have been upgraded to the 0.6.5 version where these issues has been corrected. _______________________________________________________________________ References: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2011-3362 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2011-3504 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2011-3973 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2011-3974 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2011-3892 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2011-3893 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2011-3895 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2011-4351 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2011-4352 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2011-4353 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2011-4364 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2011-4579 _______________________________________________________________________ Updated Packages: Mandriva Linux 2010.1: 76f5e3a4f91e96e5ba189d5b5841537c 2010.1/i586/ffmpeg-0.6.5-0.1mdv2010.2.i586.rpm 8ef35b10c5424f0426a883ec4e45c955 2010.1/i586/libavformats52-0.6.5-0.1mdv2010.2.i586.rpm 9d6f71fbc09e19c8c4c585a7b68a7dbb 2010.1/i586/libavutil50-0.6.5-0.1mdv2010.2.i586.rpm e23906f8e8ba32a8d045a22dff998680 2010.1/i586/libffmpeg52-0.6.5-0.1mdv2010.2.i586.rpm 807975400e7e27acb302f65e963e7637 2010.1/i586/libffmpeg-devel-0.6.5-0.1mdv2010.2.i586.rpm 8966bf8167413bae2257ce348487f92c 2010.1/i586/libffmpeg-static-devel-0.6.5-0.1mdv2010.2.i586.rpm 5e74f9d11c703f2b0cfa478d56252631 2010.1/i586/libpostproc51-0.6.5-0.1mdv2010.2.i586.rpm 6acd1b55535e3e198252efdbe35c3bb1 2010.1/i586/libswscaler0-0.6.5-0.1mdv2010.2.i586.rpm d2fa2388afa05744216322c07e643db0 2010.1/SRPMS/ffmpeg-0.6.5-0.1mdv2010.2.src.rpm Mandriva Linux 2010.1/X86_64: e3c5a778ee768e51333705dc6174f778 2010.1/x86_64/ffmpeg-0.6.5-0.1mdv2010.2.x86_64.rpm 962e01f7fa44c306ce9b20d91e6349b9 2010.1/x86_64/lib64avformats52-0.6.5-0.1mdv2010.2.x86_64.rpm ca6036a91e3dbdfd788c0f6e6bd909f5 2010.1/x86_64/lib64avutil50-0.6.5-0.1mdv2010.2.x86_64.rpm f20c014495e8956f94fe52544bf15fe1 2010.1/x86_64/lib64ffmpeg52-0.6.5-0.1mdv2010.2.x86_64.rpm 66512d0d4a7b8b26dd91a49153dac0e8 2010.1/x86_64/lib64ffmpeg-devel-0.6.5-0.1mdv2010.2.x86_64.rpm ee7bf41983b6a493e3ba2560db2b6d73 2010.1/x86_64/lib64ffmpeg-static-devel-0.6.5-0.1mdv2010.2.x86_64.rpm ecb6241b62e646951400e0c018411ebe 2010.1/x86_64/lib64postproc51-0.6.5-0.1mdv2010.2.x86_64.rpm 02acf40f10ea8a52b57bff736b3e00bc 2010.1/x86_64/lib64swscaler0-0.6.5-0.1mdv2010.2.x86_64.rpm d2fa2388afa05744216322c07e643db0 2010.1/SRPMS/ffmpeg-0.6.5-0.1mdv2010.2.src.rpm _______________________________________________________________________ To upgrade automatically use MandrivaUpdate or urpmi.
