Why do you count packages in the "universe"? I thought that the Ubuntu security team does not support them. https://ubuntu.com/16-04 says nothing about ESM coverage of packages in the "universe", and this does not imply such coverage. Also see comments in sources.list (APT) for the "universe":
## N.B. software from this repository is ENTIRELY UNSUPPORTED by the Ubuntu
## team. Also, please note that software in universe WILL NOT receive any
## review or updates from the Ubuntu security team.
