VERY SERIOUS Windows Vulnerability

Ilfak Guilfanov, well known in "reverse engineering" circles for his wildly popular IDA Disassembler, needed a temporary patch for his own system due to the seriousness of the WMF vulnerability (see RED box below) . . . so he wrote one!

Download Ilfak's Temporary WMF Patch291 kb — for Windows 2000, XP, 64-bit XP and 2003 server This safely and "dynamically patches" the vulnerable function in Windows to neuter it and, after rebooting, renders any Windows 2000, XP, 64-bit XP and 2003 systems completely invulnerable to exploitation of the Windows Metafile vulnerability. Please Note: Unlike the "DLL unregister" recommendation offered by Microsoft (see RED box below) Ilfak's patch completely eliminates the vulnerability.

Therefore, until Microsoft is able to update and repair their vulnerable GDI32.DLL, this is what you should use. You do NOT need to unregister the DLL as described in the RED box below.

You SHOULD REMOVE THIS PATCH to restore full functionality to Windows Metafile processing once WIndows has been officially updated and repaired.

To Remove: Simply open the Windows Control Panel "Add/Remove Programs", where you will find the "Windows WMF Metafile Vulnerability HotFix" listed. Remove it, then reboot.
