 Mandriva Linux Security Advisory                         MDVSA-2013:079
 https://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.
