| Detailed Description |
The hotfix (Q266433) for the multiple LPC and LPC Ports vulnerabilities has not been applied on the remote Windows host. LPC (Local Procedure Call) is a message-passing service provided by Windows NT 4.0 and Windows 2000 that allows threads and processes to communicate with each other. And every LPC has a collection of communications channels called LPC ports.
Several vulnerabilities have been identified in the Windows NT 4.0 and Windows 2000 implementations of LPC and LPC ports, and these problems give rise to four specific vulnerabilities:
- The "Invalid LPC Request" vulnerability.
- The "LPC Memory Exhaustion" vulnerability.
- The "Predictable LPC Message Identifier" vulnerability.
- A new variant of the previously-reported "Spoofed LPC Port Request" vulnerability.
These vulnerabilities allows an attacker to gain elevated privileges on the system, or to crash it remotely.
* Note: This check requires an account with Guest or upper privileges which can access the registry of the remote host to scan. Absence of these condition will result in the check not being performed and a False Negative for all vulnerable hosts.
* Platforms Affected:
Microsoft Windows NT, 2000

Apply the appropriate patch for your system, as listed in Microsoft Security Bulletin MS00-070. See References.
* Note: The Windows NT 4.0 patch can be installed on systems running Service Pack 6a, and will be included in Service Pack 7. The Windows 2000 patch can be installed on systems with or without Service Pack 1, and will be included in Service Pack 2. |
