Microsoft Office PICT Image Converter (CVE-2010-3946) Integer Overflow Vulnerability

Microsoft Office is prone to a remote integer-overflow vulnerability because the software fails to perform adequate boundary-checks on user-supplied data.

An attacker can exploit this issue by enticing an unsuspecting user into opening an Office document that contains a specially crafted PICT image.

Successfully exploiting this issue allows attackers to execute arbitrary code in the privilege of the currently logged in user. Failed exploit attempts will result in a denial-of-service condition.
