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.

Do not accept communications that originate from unknown or untrusted sources.

To reduce the likelihood of successful exploits, never handle files or visit sites of questionable integrity or follow links provided by unfamiliar or untrusted sources.
