Microsoft Windows is prone to a privilege-escalation vulnerability.
Successful exploits may allow attackers to elevate their privileges to LocalSystem, which would facilitate the complete compromise of affected computers.
The issue affects the following:
Windows XP SP2
Windows Server 2003
Windows Server 2008
Permit local access for trusted individuals only. Where possible, use restricted environments and restricted shells.
To reduce the likelihood of attacks, allow access to trusted individuals only and implement restricted environments and privileges.
Permit privileged access for trusted individuals only.
Since exploits require code to be run in an authenticated context, grant only trusted users privileged access to affected applications. This will reduce the chance of successful exploits.
The vendor has released an advisory and updates. Please see the references for more information.
