Recommendations

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 requests that include NOP sleds and unexplained incoming and outgoing traffic

Do not accept or execute files from untrusted or unknown sources.
To reduce the likelihood of successful exploits, do not open files that originate from untrusted sources.

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.

Run all software as a nonprivileged user with minimal access rights.
To limit the impact of latent vulnerabilities, configure database servers and other applications to run as a nonadministrative user with minimal access rights.

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