Looks like MS is issuing an out of band patch. Though they aren't saying specifically what vulnerability it addresses.

Microsoft will issue an out-of-band patch on Monday for a critical vulnerability in all of the current versions of Windows. The company didn't identify which flaw it will be patching, but the description of the vulnerability is a close match to the LNK flaw that attackers have been exploiting for several weeks now, most notably with the Stuxnet Malware.
