This update resolves the 'Unchecked Buffer in SNMP Service Could Enable Arbitrary Code to be Run' security vulnerability in Windows 2000, and is discussed in Microsoft Security Bulletin MS02-006. This patch prevents a malicious user from running code of their choice or launching a Denial of Service (DoS) attack on your computer.

The vulnerability exists because a component of the SNMP agent service that interprets incoming commands contains an unchecked buffer. 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.
