MITIGATION

 

The aforementioned issues were validated by product team engineers. The following product updates have been made available to customers to remediate these issues:

  • SEP 14.2 RU1
  • SEP 14.2 RU2
  • SEPM 14.2 RU2
  • SEP SBE 12.1 RU6 MP10d (12.1.7510.7002)
  • SMSMSE 7.9.x (or apply the HF provided in the link)

The listed product updates 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.
