Use-after-free vulnerability in the matroska_read_seek function in libavformat/matroskadec.c in FFmpeg before 2.5.1, as used in Google Chrome before 40.0.2214.91, allows remote attackers to cause a denial of service or possibly have unspecified other impact via a crafted Matroska file that triggers improper maintenance of tracks data.
libavcodec/utvideodec.c in FFmpeg before 2.5.2 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 (1) restore_median and (2) restore_median_il functions.
The vmd_decode function in libavcodec/vmdvideo.c in FFmpeg before 2.5.2 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.
libavcodec/xface.h in FFmpeg before 2.5.2 establishes certain digits and words array dimensions that do not satisfy a required mathematical relationship, which allows remote attackers to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact via crafted X-Face image data.
The ff_hevc_decode_nal_sps function in libavcodec/hevc_ps.c in FFMpeg before 2.1.6, 2.2.x through 2.3.x, and 2.4.x before 2.4.4 allows remote attackers to cause a denial of service (out-of-bounds access) via a crafted .bit file.
The raw_decode function in libavcodec/rawdec.c in FFMpeg before 2.1.6, 2.2.x through 2.3.x, and 2.4.x before 2.4.4 allows remote attackers to cause a denial of service (out-of-bounds heap access) and possibly have other unspecified impact via a crafted .cine file that triggers the avpicture_get_size function to return a negative frame size.
The decode_ihdr_chunk function in libavcodec/pngdec.c in FFMpeg before 2.1.6, 2.2.x through 2.3.x, and 2.4.x before 2.4.4 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.
The mjpeg_decode_app function in libavcodec/mjpegdec.c in FFMpeg before 2.1.6, 2.2.x through 2.3.x, and 2.4.x before 2.4.4 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.
libavcodec/pngdec.c in FFmpeg before 2.4.2 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.
Integer underflow in libavcodec/cinepak.c in FFmpeg before 2.4.2 allows remote attackers to cause a denial of service (out-of-bounds access) or possibly have unspecified other impact via crafted Cinepak video data.
