Ilfak Guilfanov, who has brilliantly come up with the ONLY legitimate patch for the WMF exploit, is getting hammered with hits on his site. Hence, you will have a very hard time getting to it.
I’ve thrown the hotfix up on our servers for people looking for an alternate download site.
This is unofficial, it’s enough to just get everyone by until Ilfak can get things up again.
