Vulnerability discussion

An Ubuntu operating system release is considered "supported" if the vendor continues to provide security patches for the product. With an unsupported release, it will not be possible to resolve security issues discovered in the system software.

Check content

Verify the version of the Ubuntu operating system is vendor supported. Check the version of the Ubuntu operating system with the following command: # cat /etc/lsb-release DISTRIB_RELEASE=16.04 DISTRIB_CODENAME=xenial DISTRIB_DESCRIPTION="Ubuntu 16.04.1 LTS" Current End of Life for Ubuntu 16.04 LTS is April 2021. If the release is not supported by the vendor, this is a finding.

Upgrade to a supported version of the Ubuntu operating system.

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
