Title: Microsoft Windows 2000 Telnet Service DoS Vulnerability
Severity: MODERATE
Description:
Microsoft Windows 2000 ships with a telnet service. A vulnerability exists in the telnet service which could enable a client to cause the host to stop responding.
If a client makes numerous connections to the host in a particular way, the telnet service could begin to consume all available system resources and eventually crash.
This vulnerability is caused by the way handlers function in Windows 2000. Under certain conditions, the handlers are not properly reinstated to the system for reuse.
No further technical details have been provided.
A restart of the service is required in order to regain normal functionality.
