A vulnerability, which was classified as critical, has been found in FFmpeg up to 2.8.3 (Multimedia Processing Software). Affected by this issue is the function ff_get_buffer of the file libavcodec/utils.c of the component MOV File Handler. The manipulation of the argument width/height with an unknown input leads to a memory corruption vulnerability. Using CWE to declare the problem leads to CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. Impacted is confidentiality, integrity, and availability. CVE summarizes:

The ff_get_buffer function in libavcodec/utils.c in FFmpeg before 2.8.4 preserves width and height values after a failure, which allows remote attackers to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact via a crafted .mov file.

The weakness was shared 12/24/2015 by Gynvael Coldwind (j00ru) (Website). The advisory is shared for download at git.videolan.org. This vulnerability is handled as CVE-2015-8663 since 12/23/2015.
