Summary: Updated ffmpeg packages fix security vulnerabilities

Details: A use-after-free vulnerability in FFmpeg before 1.1.9 involving seek operations on video data could allow remote attackers to cause a denial of service (CVE-2012-5150). The tak_decode_frame function in libavcodec/takdec.c in FFmpeg before 1.1.9 does not properly validate a certain bits-per-sample value, which allows remote attackers to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact via crafted TAK (aka Tom's lossless Audio Kompressor) data (CVE-2014-2097). libavcodec/wmalosslessdec.c in FFmpeg before 1.1.9 uses an incorrect data-structure size for certain coefficients, which allows remote attackers to cause a denial of service (memory corruption) or possibly have unspecified other impact via crafted WMA data (CVE-2014-2098). The msrle_decode_frame function in libavcodec/msrle.c in FFmpeg before 1.1.9 does not properly calculate line sizes, which allows remote attackers to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact via crafted Microsoft RLE video data (CVE-2014-2099). The mpegts_write_pmt function in the MPEG2 transport stream (aka DVB) muxer (libavformat/mpegtsenc.c) in FFmpeg before 1.1.9 allows remote attackers to have unspecified impact and vectors, which trigger an out-of-bounds write (CVE-2014-2263). An integer overflow in LZO decompression in FFmpeg before 1.1.12 allows remote attackers to have an unspecified impact by embedding compressed data in a video file (CVE-2014-4610). This updates provides ffmpeg version 1.1.12, which fixes these issues and several other bugs which were corrected upstream.
