Recommendations

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.

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. This may indicate exploit attempts or activity that results from a successful exploit.

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