Security Update, October 7, 2000
This update resolves the "Multiple LPC and LPC Ports" security vulnerability in Windows 2000, and is discussed in Microsoft Security Bulletin MS00-070. Download now to help 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.

Local Procedure Call (LPC) is a message-passing service provided by Windows 2000. 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 2000 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.

For more information on this vunerability, please read Microsoft Security Bulletin MS00-070 (This site is in English.)
