-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 _______________________________________________________________________ Mandriva Linux Security Advisory MDVSA-2012:076 http://www.mandriva.com/security/ _______________________________________________________________________ Package : ffmpeg Date : May 15, 2012 Affected: 2011. _______________________________________________________________________ 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). Multiple input validations in the decoders/ demuxers for Westwood Studios VQA, Apple MJPEG-B, Theora, Matroska, Vorbis, Sony ATRAC3, DV, NSV, files could lead to the execution of arbitrary code (CVE-2011-3929, CVE-2011-3936, CVE-2011-3937, CVE-2011-3940, CVE-2011-3945, CVE-2011-3947, CVE-2012-0853, CVE-2012-0858). The updated packages have been upgraded to the 0.7.12 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-2011-3892 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-2011-3929 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2011-3936 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2011-3937 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2011-3940 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2011-3945 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2011-3947 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-2011-4351 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 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2012-0853 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2012-0858 http://ffmpeg.org/security.html _______________________________________________________________________ Updated Packages: Mandriva Linux 2011: 406a90f3c3aa705f38d562d48e295e03 2011/i586/ffmpeg-0.7.12-0.1-mdv2011.0.i586.rpm 32129d580b8038edbf9895ec4d7b2fcb 2011/i586/libavfilter1-0.7.12-0.1-mdv2011.0.i586.rpm b7f175f1035f4067c9cb94281833180b 2011/i586/libavformats52-0.7.12-0.1-mdv2011.0.i586.rpm 353614e9f64b6ae0d872d68183de1702 2011/i586/libavutil50-0.7.12-0.1-mdv2011.0.i586.rpm d8f5981968b0b6fa6533ff1c0fff3b21 2011/i586/libffmpeg52-0.7.12-0.1-mdv2011.0.i586.rpm 8afc2be1abb99a531dc264d2c2ca06f2 2011/i586/libffmpeg-devel-0.7.12-0.1-mdv2011.0.i586.rpm 3388b38d883111b7a9690c6b6e5642cd 2011/i586/libffmpeg-static-devel-0.7.12-0.1-mdv2011.0.i586.rpm eab9abe8ff0c3c8f70e0835ff5d86a16 2011/i586/libpostproc51-0.7.12-0.1-mdv2011.0.i586.rpm 56412a9d476c3afa6eddfb2213197aef 2011/i586/libswscaler0-0.7.12-0.1-mdv2011.0.i586.rpm 5c84c76529690066d76d0ab23dcd7c18 2011/SRPMS/ffmpeg-0.7.12-0.1.src.rpm Mandriva Linux 2011/X86_64: 48d4a2512c540a98a442a9c1d502967e 2011/x86_64/ffmpeg-0.7.12-0.1-mdv2011.0.x86_64.rpm d2317215c418f1dc2bbd5501ded9dfa8 2011/x86_64/lib64avfilter1-0.7.12-0.1-mdv2011.0.x86_64.rpm 7cce3f5255ff1c8443e915fd9dd0cc40 2011/x86_64/lib64avformats52-0.7.12-0.1-mdv2011.0.x86_64.rpm 39cb1e16f40dd1c3c7a4eefd4099c5a0 2011/x86_64/lib64avutil50-0.7.12-0.1-mdv2011.0.x86_64.rpm 374bf64c3811af7b1f7c87e614bba01e 2011/x86_64/lib64ffmpeg52-0.7.12-0.1-mdv2011.0.x86_64.rpm c7630d17e83608a9b9b11a62acbf55db 2011/x86_64/lib64ffmpeg-devel-0.7.12-0.1-mdv2011.0.x86_64.rpm ed5b7e42dcf2ef78b073251286fda9a9 2011/x86_64/lib64ffmpeg-static-devel-0.7.12-0.1-mdv2011.0.x86_64.rpm 4e380177dd301bca6b706eacc7a8e36b 2011/x86_64/lib64postproc51-0.7.12-0.1-mdv2011.0.x86_64.rpm 73493c74c9eb57107a9ff5451da1352e 2011/x86_64/lib64swscaler0-0.7.12-0.1-mdv2011.0.x86_64.rpm 5c84c76529690066d76d0ab23dcd7c18 2011/SRPMS/ffmpeg-0.7.12-0.1.src.rpm _______________________________________________________________________ To upgrade automatically use MandrivaUpdate or urpmi.
