If the affected application is not required to be globally accessible it is recommended that access to vulnerable computers be restricted to trusted hosts and networks.

Deploy network intrusion detection systems to monitor network traffic for malicious activity.

Network intrusion detection systems should be deployed to monitor network traffic for signs of anomalous or suspicious activity. This may indicate exploitation attempts or activity that results from successful exploitation.
Microsoft has released Microsoft Security Bulletin MS04-016 to address these issues. Please see the referenced bulletin for more information.
