304876 NNTP Service in Windows NT 4.0 Contains Memory Leak
The Network News Transfer Protocol (NNTP) service in Windows 2000 contains a memory leak in a routine that processes news postings. Each time a posting that contains a particular construction is processed, the memory leak causes a small amount of memory to no longer be available for use. If an attacker were to send a large number of posts, the server memory could be depleted to the point that normal service would be disrupted. An affected server could be restored to normal service by rebooting the server.
The default configuration of NNTP is not affected by this vulnerability because no newsgroups are configured by default.
This vulnerability would not enable an attacker to usurp any administrative control or compromise data on the computer.
To resolve this problem, obtain the latest service pack for Windows 2000. For additional information, click the following article number to view the article in theMicrosoft Knowledge Base:
