Vulnerabilities
A Vulnerability is a state in a computing system (or set of systems) which either (a) allows an attacker to execute commands as another user, (b) allows an attacker to access data that is contrary to the specified access restrictions for that data, (c) allows an attacker to pose as another entity, or (d) allows an attacker to conduct a denial of service.Advisories relating to Symantec products may be viewed here.

Recommendations
-
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 exploitation.
-
Run all software as a nonprivileged user with minimal access rights.To reduce the impact of a successful attack, run the browser with the minimal amount of privileges required for functionality.
-
Deploy network intrusion detection systems to monitor network traffic for malicious activity.Deploy NIDS to detect and block attacks and anomalous activity such as requests containing suspicious URI sequences. Since the webserver may log such requests, review its logs regularly.
-
Do not follow links provided by unknown or untrusted sources.To reduce the likelihood of successful exploits, never visit sites of questionable integrity or follow links provided by unfamiliar or untrusted sources.
