Forecast for the 10th, the WMF security exploit was prioritized and patched overnight. If you’re reading this over a morning cup of joe, you probably should already have it installed: there’s no reason not to have “automatically download new updates” enabled on your computer. Never the less, going to windowsupdate.microsoft.com and downloading patch KB912919 will get your machine prophylacticized as well. Unfortunately, it doesn’t yet appear to be available through 62NDS’ Firefox Windows Update page, though.
