Message-Id: <E1T765F-0002zx-FU@titan.mandriva.com> Date: Thu, 30 Aug 2012 16:51:01 +0200 From: security@...driva.com To: full-disclosure@...ts.grok.org.uk Subject: [ MDVSA-2012:074-1 ] ffmpeg -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 _______________________________________________________________________ Mandriva Linux Security Advisory MDVSA-2012:074-1 http://www.mandriva.com/security/ _______________________________________________________________________ Package : ffmpeg Date : August 30, 2012 Affected: Enterprise Server 5.0 _______________________________________________________________________ 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). 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 0.5.9 version where these issues has been corrected. Additionally a couple of packages needed to be rebuilt for the new ffmpeg version and is also being provided with this advisory. Update: A missing dependency was discovered which prevented the sox library from installing properly. This updated advisory provided the missing libwavpack1 and lib64wavpack1 packages. _______________________________________________________________________ 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-2011-3893 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 Enterprise Server 5: e5eb142288909af6edc2a4e8de5da929 mes5/i586/libwavpack1-4.50.1-1.1mdvmes5.2.i586.rpm 3c13b4549f16fc37a1f1a2c26eb4b0ca mes5/i586/libwavpack-devel-4.50.1-1.1mdvmes5.2.i586.rpm a2b9c040c0716a2f857db06216a804bb mes5/i586/wavpack-4.50.1-1.1mdvmes5.2.i586.rpm f918f7bee89f6b3683709dfe936208df mes5/SRPMS/wavpack-4.50.1-1.1mdvmes5.2.src.rpm Mandriva Enterprise Server 5/X86_64: fa81de9663db8946cd5b3e86a8696291 mes5/x86_64/lib64wavpack1-4.50.1-1.1mdvmes5.2.x86_64.rpm b31e5c045f36791a2b2dea8b9a9052fb mes5/x86_64/lib64wavpack-devel-4.50.1-1.1mdvmes5.2.x86_64.rpm 35acbdb69bd2d53c1c425ae75273380d mes5/x86_64/wavpack-4.50.1-1.1mdvmes5.2.x86_64.rpm f918f7bee89f6b3683709dfe936208df mes5/SRPMS/wavpack-4.50.1-1.1mdvmes5.2.src.rpm _______________________________________________________________________ To upgrade automatically use MandrivaUpdate or urpmi.
