- Microsoft Windows is prone to a remote code-execution vulnerability. An attacker can leverage this issue to execute arbitrary code in the context of the currently logged-in user. Failed exploit attempts will likely result in denial of service conditions.

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 exploits.
Run all software as a nonprivileged user with minimal access rights.To reduce the impact of latent vulnerabilities, run the application with the minimal amount of privileges required for functionality.
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. This includes but is not limited to unexplained incoming and outgoing traffic. This may indicate exploit attempts or activity that results from successful exploits.
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.
