Recommendations

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 a successful attack.

Run all software as a nonprivileged user with minimal access rights.
Run all non-administrative software as a non-administrative user with the least amount of privileges required to successfully operate. This will greatly reduce the potential damage that successful exploitation may achieve.

Deploy network intrusion detection systems to monitor network traffic for malicious activity.
Deploy NIDS to monitor network traffic for signs of anomalous or suspicious activity. This may indicate exploit attempts or activity that results from successful exploits.

Updates are available. Please see the references or vendor advisory for more information.
