Windows 2000 SNMP DoS

I just verified that a bug I found a while (read: a year) ago was fixed in
Windows 2000 service pack 3. I didn't get a notification from MS about the
fix so apologies for the delay in posting the full details.
The bug is the one referenced at
If you send SNMP queries for printer - related objects in the LANMAN MIB,
the SNMP service leaks around 30MB of memory per request, but only if the
print spooler service is *not* running. This eventually brings the whole
server down, with a powercycle needed to restart.
A lengthier advisory can be found at
Once again, this is an old bug, fixed in Windows 2000 SP3. I'm publishing
this so folks with pre-sp3 boxes are aware of the issue.
