  - CVE-2017-6324: The Symantec Messaging Gateway, when processing a specific email attachment, can
  allow a malformed or corrupted Word file with a potentially malicious macro through despite the
  administrator having the 'disarm' functionality enabled. This constitutes a 'bypass' of the
  disarm functionality resident to the application.

  - CVE-2017-6325: The Symantec Messaging Gateway can encounter a file inclusion vulnerability,
  which is a type of vulnerability that is most commonly found to affect web applications that rely
  on a scripting run time. This issue is caused when an application builds a path to executable
  code using an attacker-controlled variable in a way that allows the attacker to control which
  file is executed at run time. This file inclusion vulnerability subverts how an application loads
  code for execution. Successful exploitation of a file inclusion vulnerability will result in
  remote code execution on the web server that runs the affected web application.

  - CVE-2017-6326: 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.");
