Description Andrej Nemec 2016-10-04 11:06:59 UTC

An exploitable out-of-bounds write vulnerability exists in the XMP image handling functionality of the FreeImage library.

A specially crafted XMP file can cause an arbitrary memory overwrite resulting in code execution. An attacker can provide a malicious image to trigger this vulnerability.
