We just got the word that Microsoft is going out of normal update cycle to release security update MS06-001 today. This will fix the WMF vulnerability on XP, 2003 and 2000 (sp4) systems.Microsoft originally planned to release the update on next Tuesday, but they finished testing early.Everybody was hoping they would get the patch out before a major attack would start. Now it looks like they succeeded in doing just that. Well done.Update: The patch can now be downloaded from here. It seems to co-exist fine with the REGSVR32 workaround and the Ilfak patch.
