As seen on slashdot, it looks like a whack of new updates for windows have been posted to the Microsoft technet update page. Included in the goodness are Shell, NNTP, SMTP, Zip, and a few others. Doesn't look like it's on windows update yet, but you can download the hotfixes from the linked page. Not all these affect all versions, and in a couple of cases it looks like you're safe if you are running xpsp2, but not all.
