Block external access at the network boundary, unless external parties require service.
If global access isn't needed, filter access to the affected computer at the network boundary. Restricting access to only trusted computers and networks might greatly reduce the likelihood of successful exploits.
Implement multiple redundant layers of security.
Use of multiple redundant layers of encryption may reduce exposure to this and other latent vulnerabilities.
Reportedly, the issue is fixed; however, Symantec has not confirmed this. Please contact the vendor for more information.
