I'd encourage everyone to quickly perform a Windows Update if you haven't already to stay protected

MS04-036: NNTP Proof of Concept exploit developed
http://isc.sans.org//diary.php?date=2004-10-15

If you were wondering how quickly you needed to apply the patches that Microsoft released a couple of days ago, please keep in mind that proof-of-concept exploit code for the Windows NNTP vulnerability (MS04-036) is publicly available. The recent Core Security advisory includes the exploit code, and provides detailed technical information about the vulnerability, which they seem to have reported to Microsoft in mid-August.

The Core Security advisory was published just hours after the patches became publicly available--this is a good illustration of the rapidly shrinking time window in which you need to apply security patches.
