Recommendations

Run all software as a nonprivileged user with minimal access rights.
To reduce the impact of latent vulnerabilities, always run nonadministrative software as an unprivileged 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 suspicious or anomalous activity. This may help detect malicious actions that an attacker may take after successfully exploiting vulnerabilities in applications. Review all applicable logs regularly.

Do not use client software to access unknown or untrusted hosts from critical systems.
Due to the nature of this issue, avoid using the client application to connect to unknown or untrusted hosts.

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