MS-ISAC CYBER SECURITY ADVISORY NUMBER:
Vulnerabilities in Microsoft PowerPoint Could Allow Remote Code Execution (MS10-004)
Six new vulnerabilities have been discovered in Microsoft PowerPoint, a program used for creating presentations. These vulnerabilities can be exploited by opening a specially crafted PowerPoint presentation (.PPT or .PPS file) received as an email attachment, or by visiting a web site that is hosting a specially crafted PowerPoint file. Successful exploitation could allow an attacker to gain the same privileges as the logged on user. Depending on the privileges associated with the user, an attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.

Six new vulnerabilities have been identified in Microsoft PowerPoint that could allow remote code execution. The vulnerabilities can be exploited by opening a specially crafted PowerPoint presentation (.PPT or .PPS). These vulnerabilities can be exploited via an email attachment or through the Web. In the email based scenario, the user would have to open the specially crafted PowerPoint presentation as an email attachment. In the Web based scenario, a user would visit a website and then open the specially crafted PowerPoint presentation that is hosted on the page.
Successful exploitation could allow an attacker to gain the same privileges as the logged on user. Depending on the privileges associated with the user, an attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.
We recommend the following actions be taken:
- Apply appropriate patches provided by Microsoft to vulnerable systems immediately after appropriate testing.
- 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 email attachments from unknown or un-trusted sources.
- Consider using the Microsoft Office Isolated Conversion Environment (MOICE - http://support.microsoft.com/kb/935865) to mitigate some of the vulnerabilities identified in this advisory.
