Detail

Updated ffmpeg packages fix security vulnerabilities:

The tak_decode_frame function in libavcodec/takdec.c in FFmpeg before 2.0.4 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 2.0.4 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 2.0.4 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 2.0.4 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 2.0.5 allows remote attackers to have an unspecified impact by embedding compressed data in a video file (CVE-2014-4610).

A heap-based buffer overflow in the encode_slice function in libavcodec/proresenc_kostya.c in FFmpeg before 2.0.6 can cause a crash, allowing a malicious image file to cause a denial of service (CVE-2014-5271).

libavcodec/iff.c in FFmpeg before 2.0.6 allows an attacker to have an unspecified impact via a crafted iff image, which triggers an out-of-bounds array access, related to the rgb8 and rgbn formats (CVE-2014-5272).

libavcodec/mjpegdec.c in FFmpeg before 2.0.6 considers only dimension differences, and not bits-per-pixel differences, when determining whether an image size has changed, which allows remote attackers to cause a denial of service (out-of-bounds access) or possibly have unspecified other impact via crafted MJPEG data (CVE-2014-8541).

libavcodec/utils.c in FFmpeg before 2.0.6 omits a certain codec ID during enforcement of alignment, which allows remote attackers to cause a denial of service (out-of-bounds access) or possibly have unspecified other impact via crafted JV data (CVE-2014-8542).

libavcodec/mmvideo.c in FFmpeg before 2.0.6 does not consider all lines of HHV Intra blocks during validation of image height, which allows remote attackers to cause a denial of service (out-of-bounds access) or possibly have unspecified other impact via crafted MM video data (CVE-2014-8543).

libavcodec/tiff.c in FFmpeg before 2.0.6 does not properly validate bits-per-pixel fields, which allows remote attackers to cause a denial of service (out-of-bounds access) or possibly have unspecified other impact via crafted TIFF data (CVE-2014-8544).

libavcodec/pngdec.c in FFmpeg before 2.0.6 accepts the monochrome-black format without verifying that the bits-per-pixel value is 1, which allows remote attackers to cause a denial of service (out-of-bounds access) or possibly have unspecified other impact via crafted PNG data (CVE-2014-8545).

Integer underflow in libavcodec/cinepak.c in FFmpeg before 2.0.6 allows remote attackers to cause a denial of service (out-of-bounds access) or possibly have unspecified other impact via crafted Cinepak video data (CVE-2014-8546).

libavcodec/gifdec.c in FFmpeg before 2.0.6 does not properly compute image heights, which allows remote attackers to cause a denial of service (out-of-bounds access) or possibly have unspecified other impact via crafted GIF data (CVE-2014-8547).

Off-by-one error in libavcodec/smc.c in FFmpeg before 2.0.6 allows remote attackers to cause a denial of service (out-of-bounds access) or possibly have unspecified other impact via crafted Quicktime Graphics (aka SMC) video data (CVE-2014-8548).

This updates provides ffmpeg version 2.0.6, which fixes these issues and several other bugs which were corrected upstream.
