  - CVE-2017-6327: The Symantec Messaging Gateway can encounter an issue of remote code execution,
  which describes a situation whereby an individual may obtain the ability to execute commands
  remotely on a target machine or in a target process. In this type of occurrence, after gaining
  access to the system, the attacker may attempt to elevate their privileges.

  - CVE-2017-6328: The Symantec Messaging Gateway can encounter an issue of cross site request
  forgery (also known as one-click attack and is abbreviated as CSRF or XSRF), which is a type of
  malicious exploit of a website where unauthorized commands are transmitted from a user that the
  web application trusts. A CSRF attack attempts to exploit the trust that a specific website has
  in a user's browser.");
