When an Office document containing malformed a property field is opened with an Office application, system memory can be corrupted in a way that may allow an attacker to execute arbitrary code. Property fields include, but are not limited to document title, subject, and author.

More information, including a list of affected Office applications, is available in Microsoft Security Bulletin MS06-038.
