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 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.

Run all software as a nonprivileged user with minimal access rights.
To limit the consequences of successful exploits, run server processes within a restricted environment using facilities such as chroot or jail.

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