The aforementioned issues were validated by product team engineers. A set of product security updates to mitigate the listed issues are as follows:
- Norton Security for Windows version 22.16.3 (or higher)
- **Note for Window 7 users: please apply SP1 or higher
- Symantec Endpoint Protection (SEP) version 14.2 RU1
- Symantec Endpoint Protection Manager (SEPM) version 14.2 RU1

Note that the latest releases of the mentioned products are available to customers through normal support channels. At this time, Symantec is not aware of any exploitations or adverse customer impact from these issues.
Symantec recommends the following measures to reduce risk of attack:
- Restrict access to administrative or management systems to authorized privileged users.
- Restrict remote access to trusted/authorized systems only.
- Run under the principle of least privilege, where possible, to limit the impact of potential exploit.
- Keep all operating systems and applications current with vendor patches.
- Follow a multi-layered approach to security. At a minimum, run both firewall and anti-malware applications to provide multiple points of detection and protection for both inbound and outbound threats.
- Deploy network and host-based intrusion detection systems to monitor network traffic for signs of anomalous or suspicious activity. This may aid in the detection of attacks or malicious activity related to the exploitation of latent vulnerabilities.
