Updated ffmpeg packages fix security vulnerabilities
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).
