Windows 2000 NNTP Denial of Service Vulnerability Patch MS01-043 (Windows)

This update resolves a denial of service vulnerability in Windows 2000 computers running the Network News Transfer Protocol (NNTP) service. This denial of service vulnerability exists because the NNTP service in Windows 2000 contains a memory leak. If a malicious user sends a large amount of specially malformed data to an affected server, it can deplete the memory that is available to the server, which can cause the server to stop performing.
