Force a Windows Update and patch a “serious security hole” ASAP 

Looks like there’s a serious security hole in Windows that is based on a type of font. Presumably, this goes undetected by anti-virus software and can be activated by opening up a Word document.

Don’t wait. Go to Windows Update right now and force a “Check for Updates”, then install the patches.

More details:

The software giant said in an advisory Monday that the vulnerability, if exploited, could “allow remote code execution if a user opens a specially crafted document or visits an untrusted webpage that contains embedded OpenType fonts.”
