Some use untill the patch becomes available SOURCE Microsoft and CERT.ORG have issued bulletins on the Windows Metafile vulnerability: http://www.microsoft.com/technet/security/advisory/912840.mspx http://www.kb.cert.org/vuls/id/181038 Microsoft's bulletin confirms that this vulnerability applies to all the main versions of Windows: Windows ME, Windows 2000, Windows XP and Windows 2003. They also list the REGSVR32 workaround. It's a good idea to use this while waiting for a patch. To quote Microsoft's bulletin: Un-register the Windows Picture and Fax Viewer (Shimgvw.dll) 1. Click Start, click Run, type "regsvr32 -u %windir%\system32\shimgvw.dll" (without the quotation marks), and then click OK. 2. A dialog box appears to confirm that the un-registration process has succeeded. Click OK to close the dialog box. Impact of Workaround: The Windows Picture and Fax Viewer will no longer be started when users click on a link to an image type that is associated with the Windows Picture and Fax Viewer. To undo this change, re-register Shimgvw.dll by following the above steps. Replace the text in Step 1 with âregsvr32 %windir%\system32\shimgvw.dllâ (without the quotation marks).
