Summary
This script checks and reports an outdated or end-of-life scan engine for the following environments: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

Solution type: VendorFix
Vendorfix
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.
