Mitigations/Workarounds
Symantec Security Response has released an IPS/IDS signature, Signature ID 23283, to detect and block attempts to exploit this issue. Signature is available through normal update channels.

Best Practices
As part of normal best practices, Symantec strongly recommends:

• Restrict access to administration or management systems to privileged users.
• Restrict remote access, if it is required, to trusted/authorized systems only.
• Run under the principle of least privilege where possible to limit the impact of potential exploits.
• Keep all operating systems and applications updated with the latest vendor patches.
• Follow a multi-layered approach to security. Run both firewall and antivirus applications, at a minimum, to provide multiple points of detection and protection to both inbound and outbound threats.
• Deploy network intrusion detection systems to monitor network traffic for signs of anomalous or suspicious activity. This may aid in detection of attacks or malicious activity related to exploitation of latent vulnerabilities
