Don't wait for Microsoft to fix WMF flaw
Windows users should install an unofficial security patch now, without waiting for Microsoft to make its move, advised security researchers at The SANS Institute's Internet Storm Center (ISC).
Their recommendation follows a new wave of attacks on a flaw in the way versions of Windows from 98 through XP handle malicious files in the WMF (Windows Metafile) format. One such attack arrives in an e-mail message entitled "happy new year," bearing a malicious file attachment called "HappyNewYear.jpg" that is really a disguised WMF file, security research companies including iDefense and F-Secure. said Sunday. Even though the file is labelled as a JPEG, Windows recognizes the content as a WMF and attempts to execute the code it contains.
