Permit local access for trusted individuals only. Where possible, use restricted environments and restricted shells.
Allow only trusted and accountable individuals to have local interactive access to the vulnerable computer.
Block external access at the network boundary, unless external parties require service.
If global access isn't needed, filter access to the affected computer at the network boundary. Restricting access to only trusted computers and networks might greatly reduce the likelihood of successful exploits.
Deploy network intrusion detection systems to monitor network traffic for malicious activity.
Deploy NIDS to detect and block attacks and anomalous activity such as requests containing suspicious URI sequences. Since the webserver may log such requests, review its logs regularly.
Set web browser security to disable the execution of script code or active content.
Since a successful exploit of some of these issues requires malicious code to execute in web clients, consider disabling support for script code and active content within the client browser. Note that this mitigation tactic might adversely affect legitimate websites that rely on the execution of browser-based script code.
Updates are available. Please see the references or vendor advisory for more information.
