Description:
 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.
