SYMPTOMS

It may be possible for a non-privileged user to elevate their existing security context to that of a service that was started by Service Control Manager (SCM). A malicious user could use a named pipe connection to instruct a Windows 2000-based computer to start a pre-defined process that has a security permission higher than the actual security permission that is assigned to the user.
