Symantec recommends customers immediately apply the latest Security Update to protect against potential related attacks.

To help reduce the risks associated with this vulnerability Symantec recommends the following best practices:

  • Restrict access to administration or management systems to privileged users only, with additional restricted access to the physical host system(s) if possible.
  • 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.
  • Be cautious visiting unknown or untrusted websites or following unknown URL links.
  • Do not open attachments or executables from unknown sources or that you didn't request or were unaware of. Always err on the side of caution. Even if the sender is known, the source address may be spoofed.
