Further to my blog yesterday about the VML Exploit in Internet Explorer, Microsoft have released overnight (UK time) an out-of-band patch. Early news of the release was reported by Microsoft's Craig Gehre on the Microsoft Security Response Center Blog.
Microsoft clearly consider this vulnerability to be serious, since they rarely issue patches outside the normal monthly cycle.
Microsoft are taking advantage of the need to release MS06-055 by re-releasing MS06-049, which apparently needs some alterations.
