Just before the New Year, I wrote about a potential security exploit in Windows XP from WMF files. Microsoft just released a patch, ahead of their normal security fix schedule in order to close this major security hole. If you have automatic updates turned on, the update should either be available for download or already downloaded for your system. If you don’t use the Windows XP Automatic Update service, it’s time to visit Windows Update and patch your system. This is not something you want to mess around with as the potential hole can be exploited simply by opening a link to a specific type of graphic file.
