Date: Tue, 09 Apr 2013 11:22:00 +0200 From: security@...driva.com To: full-disclosure@...ts.grok.org.uk Subject: [ MDVSA-2013:079 ] ffmpeg -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 _______________________________________________________________________ Mandriva Linux Security Advisory MDVSA-2013:079 http://www.mandriva.com/en/support/security/ _______________________________________________________________________ Package : ffmpeg Date : April 9, 2013 Affected: Business Server 1.0 _______________________________________________________________________ Problem Description: Updated ffmpeg packages fix security vulnerabilities: h264: Add check for invalid chroma_format_idc (CVE-2012-0851) h263dec: Disallow width/height changing with frame threads (CVE-2011-3937) vc1dec: check that coded slice positions and interlacing match. This fixes out of array writes (CVE-2012-2796) alsdec: fix number of decoded samples in first sub-block in BGMC mode (CVE-2012-2790) cavsdec: check for changing w/h. Our decoder does not support changing w/h (CVE-2012-2777, CVE-2012-2784) indeo4: update AVCodecContext width/height on size change (CVE-2012-2787) avidec: use actually read size instead of requested size (CVE-2012-2788) wmaprodec: check num_vec_coeffs for validity (CVE-2012-2789) lagarith: check count before writing zeros (CVE-2012-2793) indeo3: fix out of cell write (CVE-2012-2776) indeo5: check tile size in decode_mb_info\(\). This prevents writing into a too small array if some parameters changed without the tile being reallocated (CVE-2012-2794) indeo5dec: Make sure we have had a valid gop header. This prevents decoding happening on a half initialized context (CVE-2012-2779) indeo4/5: check empty tile size in decode_mb_info\(\). This prevents writing into a too small array if some parameters changed without the tile being reallocated (CVE-2012-2800) dfa: improve boundary checks in decode_dds1\(\) (CVE-2012-2798) dfa: check that the caller set width/height properly (CVE-2012-2786) avsdec: Set dimensions instead of relying on the demuxer. The decode function assumes that the video will have those dimensions (CVE-2012-2801) ac3dec: ensure get_buffer\(\) gets a buffer for the correct number of channels (CVE-2012-2802) rv34: error out on size changes with frame threading (CVE-2012-2772) alsdec: check opt_order. Fixes out of array write in quant_cof. Also make sure no invalid opt_order stays in the context (CVE-2012-2775) This updates ffmpeg to version 0.10.6 which contains the security fixes above as well as other bug fixes. _______________________________________________________________________ References: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2011-3937 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2012-0851 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2012-2772 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2012-2775 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2012-2776 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2012-2777 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2012-2779 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2012-2784 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2012-2786 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2012-2787 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2012-2788 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2012-2789 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2012-2790 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2012-2793 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2012-2794 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2012-2796 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2012-2798 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2012-2800 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2012-2801 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2012-2802 https://wiki.mageia.org/en/Support/Advisories/MGASA-2012-0143 https://wiki.mageia.org/en/Support/Advisories/MGASA-2012-0331 _______________________________________________________________________ Updated Packages: Mandriva Business Server 1/X86_64: 7ec17c8836596fed6d4ffb74005d8a99 mbs1/x86_64/ffmpeg-0.10.6-1.mbs1.x86_64.rpm 7592b8465ea19657f172c72930922601 mbs1/x86_64/lib64avcodec53-0.10.6-1.mbs1.x86_64.rpm 4d067d38c2d479fe6a289766f8d9908a mbs1/x86_64/lib64avfilter2-0.10.6-1.mbs1.x86_64.rpm b72d0caaf069957fa89d8f115cd43b7a mbs1/x86_64/lib64avformat53-0.10.6-1.mbs1.x86_64.rpm e60a449813850d40a969c5b0f8bd2f62 mbs1/x86_64/lib64avutil51-0.10.6-1.mbs1.x86_64.rpm 43932d0c784ba4393782d2ce497026fd mbs1/x86_64/lib64ffmpeg-devel-0.10.6-1.mbs1.x86_64.rpm e330d6894485635f68f4748bbc32f846 mbs1/x86_64/lib64ffmpeg-static-devel-0.10.6-1.mbs1.x86_64.rpm 49acf5dfd84f71781b6aaec19220bdd1 mbs1/x86_64/lib64postproc52-0.10.6-1.mbs1.x86_64.rpm 2e1033896765ad98629f8b51f7be31a3 mbs1/x86_64/lib64swresample0-0.10.6-1.mbs1.x86_64.rpm f132771fcbc699308f8fd1ee7e88ebdb mbs1/x86_64/lib64swscaler2-0.10.6-1.mbs1.x86_64.rpm 561c540d15bb89385f98f777e3297d51 mbs1/SRPMS/ffmpeg-0.10.6-1.mbs1.src.rpm _______________________________________________________________________ To upgrade automatically use MandrivaUpdate or urpmi.
