Technical details
A stack-based buffer overflow exists in the OGWU file parser due to lack of proper validation of user-supplied data length before copying to a stack buffer. An attacker can exploit this vulnerability via a malicious OGWU file to execute arbitrary code in the context of the viewer process. User interaction is required; the attack vector is local after file delivery.
