PGP Outlook plug-in contains a flaw that allows a remote attacker to execute arbitrary code. The issue is due to the plug-in message decoding function not properly sanitizing input allowing an attacker to overwrite portions of the system memory to execute arbitrary code. This can be exploited by sending a malicious email and does not require the user to open an attachment. Arbitrary code will be run with the privileges of the person who opens the mail.

Currently, there are no known workarounds or upgrades to correct this issue. However, Network Associates has released a patch to address this vulnerability.
