Microsoft has issued a security advisory following reports of a vulnerability in PowerPoint.


Bill Sisk, security response communications manager for Microsoft, claimed that the vulnerability could allow for remote code execution if a user opens a specially crafted PowerPoint file.


The products affected are Microsoft Office PowerPoint 2000 Service Pack 3, Microsoft Office PowerPoint 2002 Service Pack 3, and Microsoft Office PowerPoint 2003 Service Pack 3. Microsoft Office PowerPoint 2007 is not affected.


Sisk said: “At this time, we are aware only of limited and targeted attacks that attempt to use this vulnerability. If you suspect that you were target for such an attack, you can scan your computer with the Windows Live OneCare safety scanner.


“The malicious PPT files are detected as Exploit:Win32/Apptom.gen. Microsoft will take the appropriate action to protect our customers, which may include providing a solution through our monthly security update release process, or an out-of-cycle security update, depending on customer needs.”
