libavcodec/tiff.c in FFmpeg before 2.4.2 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.

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.

libavcodec/mmvideo.c in FFmpeg before 2.4.2 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.

libavcodec/gifdec.c in FFmpeg before 2.4.2 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.

libavcodec/mjpegdec.c in FFmpeg before 2.4.2 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.

Off-by-one error in libavcodec/smc.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 Quicktime Graphics (aka SMC) video data.

libavcodec/on2avc.c in FFmpeg before 2.4.2 does not constrain the number of channels to at most 2, which allows remote attackers to cause a denial of service (out-of-bounds access) or possibly have unspecified other impact via crafted On2 data.

The g2m_init_buffers function in libavcodec/g2meet.c in FFmpeg before 2.1 does not properly allocate memory for tiles, which allows remote attackers to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact via crafted Go2Webinar data.

The rpza_decode_stream function in libavcodec/rpza.c in FFmpeg before 2.1 does not properly maintain a pointer to pixel data, which allows remote attackers to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact via crafted Apple RPZA data.
