DESCRIPTION:
A vulnerability has been discovered in Microsoft PowerPoint which could allow an attacker to take complete control of an affected system. The vulnerability occurs when the application parses external objects in an 'Office Art' container. Successful exploitation of the vulnerability could result in an attacker gaining the same privileges as the logged on user.

RECOMMENDATIONS:
We recommend the following actions be taken:
- Apply appropriate patches provided by Microsoft to vulnerable systems as soon as they become available.
- Run all software as a non-privileged user (one without administrative privileges) to diminish the effects of a successful attack.
- Remind users not to visit un-trusted websites or follow links provided by unknown or un-trusted sources.
- Remind users not to open e-mail attachments from unknown or un-trusted sources.
