Don't open PowerPoint presentations of uncertain origin

[HansV]

A vulnerability in Microsoft's OLE technology has been found that affects almost all versions of Windows. See Vulnerability in Microsoft OLE Could Allow Remote Code Execution. Although this vulnerability can be exploited in many kinds of files, it currently has been found only in PowerPoint presentations.

So be very careful when you receive a PowerPoint presentation that you didn't ask for or expect in your e-mail, or if you find a PowerPoint presentation on a website that you don't know well.

If you're using Windows Vista or later, and if you have UAC (User Account Control) turned on, you'll be asked for permission to run the exploit (if present of course), so if you run a PowerPoint presentation and you suddenly get a UAC prompt, think carefully before allowing it.

The article mentioned above has a link to a Microsoft Fix it that protects PowerPoint against this vulnerability, but there is no generic solution yet - I assume Microsoft will release one soon.
