Mitigation
The issue was validated by product team engineers. A Symantec Messaging Gateway
update, version 10.7.0, has been made available. To determine what version of
SMG you are using, please refer to the version number indicated on the login
screen of the application. Note that the latest releases of Symantec Messaging
Gateway 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:
o Restrict access to administrative or management systems to authorized
privileged users.
o Restrict remote access to trusted/authorized systems only.
o Run under the principle of least privilege, where possible, to limit the
impact of potential exploit.
o Keep all operating systems and applications current with vendor patches.
o 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.
o 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.
