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.
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 including unexplained incoming and outgoing traffic. This may indicate exploit attempts or activity that results from successful exploits.
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.
Do not follow links provided by unknown or untrusted sources.
Web users should be cautious about following links to sites that are provided by unfamiliar or suspicious sources. Filtering HTML from emails may help remove a possible vector for transmitting malicious links to users.
Implement multiple redundant layers of security.
Use of multiple redundant layers of encryption may reduce exposure to this and other latent vulnerabilities.
Updates are available. Please see the references or vendor advisory for more information.
