I just did a quick search on the MS Knowledge Base and the MSIE web site, and didn't find anything. Honestly, though, the flaw in question, although they say it has a high severity, I don't see it being all that serious. It's not a very well known exploit (I didn't know anything about it, and I stay on top of these things for clients), so I wouldn't get overly worried about it. If you're worried, you can follow their suggestion for a temporary solution, though I'm sure MS will release a patch sometime for it.
