Microsoft Windows NT 4.0 Patch: Multiple LPC and LPC Ports Description

This update resolves the "Multiple LPC and LPC Ports" security vulnerability in Windows NT 4.0. Local Procedure Call (LPC) is a message-passing service provided by Windows NT 4.0. LPC ports are channels within LPC that allow threads (a series of messages that have been posted as replies to each other) within a communication process to coordinate LPC requests. Windows NT 4.0 is unable to handle unexpected LPCs properly. If a malicious user makes process requests in an invalid order, or uses invalid parameters, it could cause your computer to fail or permit a malicious user to impersonate your privileges and eavesdrop. Download now to prevent a malicious user from causing your computer to fail, impersonating your privileges, or causing the client or server to fail by posing as the client or server and sending random data. For more information, please read Microsoft Security Bulletin MS00-070 and MS00-003.
