GCVE-110-MAGEIA-2015-233

Updated avidemux packages fix security vulnerabilities: The mjpeg_decode_app function in libavcodec/mjpegdec.c in FFMpeg before 1.2.11 allows remote attackers to cause a denial of service (out-of-bounds heap access) and possibly have other unspecified impact via vectors related to LJIF tags in an MJPEG file (CVE-2014-9316). The decode_ihdr_chunk function in libavcodec/pngdec.c in FFMpeg before 1.2.11 allows remote attackers to cause a denial of service (out-of-bounds heap access) and possibly have other unspecified impact via an IDAT before an IHDR in a PNG file (CVE-2014-9317). The vmd_decode function in libavcodec/vmdvideo.c in FFmpeg before 1.2.11 does not validate the relationship between a certain length value and the frame width, which allows remote attackers to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact via crafted Sierra VMD video data (CVE-2014-9603). libavcodec/utvideodec.c in FFmpeg before 1.2.11 does not check for a zero value of a slice height, which allows remote attackers to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact via crafted Ut Video data, related to the restore_median and restore_median_il functions (CVE-2014-9604). An attacker can force a read at an invalid address in mjpegdec.c of FFmpeg, in order to trigger a denial of service (CVE-2015-1872). Use-after-free vulnerability in the ff_h264_free_tables function in libavcodec/h264.c in FFmpeg before 1.2.11 allows remote attackers to cause a denial of service or possibly have unspecified other impact via crafted H.264 data in an MP4 file, as demonstrated by an HTML VIDEO element that references H.264 data (CVE-2015-3417). Avidemux is built with a bundled set of FFmpeg libraries. The bundled FFmpeg version has been updated from 1.2.10 to 1.2.12 to fix these security issues and other bugs fixed upstream in FFmpeg.
