Detailsinfo

A vulnerability, which was classified as critical, has been found in Microsoft Windows NT 4.0/2000/XP (Operating System). Affected by this issue is an unknown code of the component Terminal Server. The manipulation with an unknown input leads to a memory corruption vulnerability. Using CWE to declare the problem leads to CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. Impacted is confidentiality, integrity, and availability. CVE summarizes:

Buffer overflow in the RPC Locator service for Microsoft Windows NT 4.0, Windows NT 4.0 Terminal Server Edition, Windows 2000, and Windows XP allows local users to execute arbitrary code via an RPC call to the service containing certain parameter information.
