A vulnerability has been discovered in the way Microsoft DirectPlay handles specially crafted Office documents. Specifically, this issue affects versions 9, 10.1, and 11.0 of DirectX. This vulnerability could allow for remote code execution if an attacker can convince a user to open a specially crafted Office document.
Successful exploitation of any of these vulnerabilities could result in an attacker gaining the ability to install programs; view, change, or delete data; or create new accounts with full administrative rights.
We recommend the following actions be taken:
- Apply appropriate patches provided by Microsoft to vulnerable systems immediately after appropriate testing.
- 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 users or suspicious e-mails from trusted sources.
- Remind users not to download or open files from un-trusted websites.
- Run all software as a non-privileged user (one without administrative privileges) to diminish the effects of a successful attack.
