I had no idea this was the case and have heard no reports of it until this blurb made it to my attention.
Apparently; even as MS played down the severity of the WMF vulnerability to us, they were taking it so seriously that they chose to over-ride the patch installation settings on machine to install this patch the instant it was received, rather than waiting for the administrator to do the deal. The subsequent reboot must have thrown a wrench into at least some operations.
So; we see Microsoft saying one thing about a security problem and acting in such a way as to convince me they knew differently all the while. So much for Trustworthy Computing".
