Microsoft windows NT 4.0 Unchecked Buffer in SNMP Service Could Enable Arbitrary Code to be Run

From Microsoft:

This update resolves the "Unchecked Buffer in SNMP Service Could Enable Arbitrary Code to be Run" security vulnerability in Windows NT® 4.0, and is discussed in Microsoft Security Bulletin MS02-006. Download now to prevent a malicious user from running code of his or her choice or launching a denial of service (DoS) attack on your computer.

The vulnerability exists because a component of the Simple Network Management Protocol (SNMP) agent service that interprets incoming commands contains an unchecked buffer (a temporary data storage area that has a limited capacity). By sending a specially malformed request, it is possible to carry out a buffer overrun attack against an affected system.

Note The SNMP service is neither installed nor running by default in any version of Windows.
