DESCRIPTION:
A security issue has been reported in Microsoft Windows, which can be
exploited by malicious, local users to gain escalated privileges.

The security issue is caused due to an error in the Windows Service
Isolation feature, which can be exploited by a process with
NetworkService privileges to gain LocalSystem privileges.

Successful exploitation requires e.g. that an attacker can control
web content hosted on an IIS server or has SQL Server administrative
privileges.

SOLUTION:
Do not run critical services with NetworkService privileges and apply
the non-security update (please see the vendor advisories for
details).
