Recommendations
  • Block external access at the network boundary, unless external parties require service.
    Filter access to the affected computer at the network boundary if global access isn't needed. Restricting access to only trusted computers and networks might greatly reduce the likelihood of a successful exploit.
  • 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 anomalous or suspicious activity. This may indicate exploit attempts or activity that results from successful exploits.
Updates are available. Please see the references or vendor advisory for more information.
