MS02-025: Exchange 2000 Exhaust CPU Resources (320436)

Medium Nessus Plugin ID 11143


It is possible to launch a denial of service attack against the remote mail server.


The remote host is running Exchange Server 2000. The remote version of this software contains a flaw that allows an attacker to cause a temporary denial of service.

To do this, the attacker needs to send an email message with malformed attributes. CPU utilization will spike at 100% until the message has been processed.


Microsoft has released a set of patches for Exchange 2000.
