Recommendations

Block external access at the network boundary, unless external parties require service.
If possible, block access to the server at the network perimeter. Allow only trusted computers and networks to have access to the resources.

Deploy network intrusion detection systems to monitor network traffic for malicious activity.
Deploy NIDS to monitor the network for suspicious requests. This may help detect attacks that try to exploit These and similar vulnerabilities. Audit all applicable logs regularly.

Run all software as a nonprivileged user with minimal access rights.
To reduce the impact of a successful exploit, run the hosting webserver in a chrooted or jailed environment with the minimal amount of privileges required for functionality.

Implement multiple redundant layers of security.
Various memory-protection schemes (such as nonexecutable and randomly mapped memory segments) may hinder an attacker’s ability to exploit this vulnerability to execute arbitrary code.

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