SP research labs (me) has found a remote kernel DoS flaw within Microsoft Windows XP SP2 fully patched, with the firewall on. I have been working with Microsoft to get a patch out for this. I notified them 5/4/2005 about the flaw, and they have been working on it since then. Microsoft told me the patch was going to be released in August. We know its only a DoS, which is kind of boring so this is why we decided to report it to Microsoft. Here is a screenshot of the crash if your interested. So, be sure to look out for our advisory and PoC the second Tuesday in August.

Thanks,
