The msrle_decode_8_16_24_32 function in msrledec.c in libavcodec in FFmpeg through 1.1.3 does not properly determine certain end pointers, which allows remote attackers to cause a denial of service (out-of-bounds array access and application crash) or possibly have unspecified other impact via crafted Microsoft RLE data.

The iff_read_header function in iff.c in libavformat in FFmpeg through 1.1.3 does not properly handle data sizes for Interchange File Format (IFF) data during operations involving a CMAP chunk or a video codec, which allows remote attackers to cause a denial of service (integer overflow, out-of-bounds array access, and application crash) or possibly have unspecified other impact via a crafted header.

sp5xdec.c in the Sunplus SP5X JPEG decoder in libavcodec in FFmpeg before 0.6.3 and libav through 0.6.2, as used in VideoLAN VLC media player 1.1.9 and earlier and other products, performs a write operation outside the bounds of an unspecified array, which allows remote attackers to cause a denial of service (memory corruption) or possibly execute arbitrary code via a malformed AMV file.
