Executive Summary:

This update resolves a newly-discovered, privately-reported vulnerability. A remote code execution vulnerability exists in the Client Service for NetWare (CSNW). By default, CSNW is not installed on any affected operating system version. Only customers who manually installed CSNW could be vulnerable to this issue. The vulnerability is documented in the ?Vulnerability Details? section of this bulletin. This service is also called Gateway Service for NetWare on Windows 2000 Server.

An attacker who successfully exploited this vulnerability could remotely take complete control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.

We recommend that customers apply the update at the earliest opportunity.
