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

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

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

avidec: use actually read size instead of requested size

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

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.
