  # nb: FEED_NAME (in global_settings.nasl) is used because this VT would run / be launched on the
  # GCS otherwise which is something we don't want to do. A different approach is (at least
  # currently) not possible because we don't know from NASL side if we're running on the GCS or on
  # a GOS running on the Enterprise TRIAL.
  # The only drawback of that approach is that a Greenbone Enterprise TRIAL with a TRIAL GSF key is
  # missed but this is currently acceptable due to the restricted time frame of the trial.

  engine for the following environments:

  - Greenbone Community Edition

  - Greenbone Enterprise TRIAL (formerly Greenbone Security Manager TRIAL / Greenbone Community
  Edition VM)

  used for this scan.

  NOTE: While this is not, in and of itself, a security vulnerability, a severity is reported to
  make you aware of a possible decreased scan coverage or missing detection of vulnerabilities on
  the target due to e.g.:

  - missing functionalities

  - missing bugfixes

  - incompatibilities within the feed");

  script_tag(name:"solution", value:"Update to the latest available stable release for your scan
  environment.

  Note: It is NOT enough to only update the scanner component. All components should be updated to
  the most recent and stable versions.

  Possible solution options depends on the installation method:

  - If using the Greenbone Enterprise TRIAL: Please do a new installation with the newest available
    version

  - If using the official Greenbone Community Containers: Please see the references on how to do an
    update of these

  - If the Greenbone Community Edition was build from sources by following the official source build
    documentation: Please see the references on how to do an update of all components

  - If using packages provided by your Linux distribution: Please contact the maintainer of the used
    distribution / repository and request updated packages

  - If using any other installation method: Please contact the provider of this solution

  Please check the references for more information.

  If you want to accept the risk of a possible decreased scan coverage or missing detection of
  vulnerabilities on the target you can set a global override for this script as described in the
  linked GSM manual.");
