Microsoft Rushes Out WMF Security Fix

Just days after announcing plans to release a patch that fixes a security vulnerability in Windows Meta File image processing on January 10, Microsoft has rushed out the update early. The company said the patch was ready earlier than expected and its decision was based on feedback from partners.

WMF, or Windows Metafile, is a vector based image format used by Microsoft's operating systems. SHIMGVW.DLL is loaded to render the images and contains a flaw that opens the door for a malformed WMF image to cause remote code execution and potentially allow for a full system compromise.
