By convincing a user to open a file from a location that is under an attacker's control, such as a USB drive or network share, a remote attacker may be able exploit this vulnerability. Exploitation of this vulnerability may result in the execution of arbitrary code or elevation of privileges.
At this time, US-CERT is aware of reports of publicly available exploit code for this vulnerability.
