1) Input validation error (CVE-ID: CVE-2013-2495)
The vulnerability allows a remote non-authenticated attacker to read and manipulate 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.
2) Buffer overflow (CVE-ID: CVE-2013-2496)
The vulnerability allows a remote non-authenticated attacker to read and manipulate data.
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.
