As reported by IntelliAdmin.com and ComputerWorld, another security hole has been found in a Microsoft product -- this time it is Windows Media Player Versions 9 and 10. Specifically, the problem is with media files that have the .asx extension. By default when you click on this file type, Windows Media Player will launch -- a compromised file would allow hackers to gain control of your PC.
IntelliAdmin.com recommends that you remove the association for Windows Media Player to play .asx files. Microsoft recommend that you upgrade to Windows Media Player 11. Microsoft says Windows Media Player 11 will work on all versions of Windows XP that have Service Pack 2. I did find one mention of possible problems if you have Windows XP Media Center 2005.
If you are looking for a fix to versions 9 or 10, it does not look like Microsoft will have something by this Tuesday, the monthly patch release from Microsoft. So just as I indicated you will likely need to wait for January's patch release for a fix in Word, you will also have to wait for January for this fix.
