Block external access at the network boundary, unless external parties require service.
Filter access to the affected computer at the network boundary if global access isn't required. Restricting access to only trusted computers and networks might greatly reduce the likelihood of a successful exploit.
Run all software as a nonprivileged user with minimal access rights.
To limit the consequences of a successful exploit, run server processes within a restricted environment using facilities such as chroot or jail.
Deploy network intrusion detection systems to monitor network traffic for malicious activity.
Deploy NIDS to monitor network traffic for signs of malicious activity such as requests containing suspicious URI sequences. Since the webserver may also log such requests, audit its logs regularly.
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.
