Upgrade Ubuntu:18.04 base-files to version 10.1ubuntu2.2 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream base-files package and not the base-files package as distributed by Ubuntu. See How to fix? for Ubuntu:18.04 relevant fixed versions and status.

The MOTD update script in the base-files package in Ubuntu 18.04 LTS before 10.1ubuntu2.2, and Ubuntu 18.10 before 10.1ubuntu6 incorrectly handled temporary files. A local attacker could use this issue to cause a denial of service, or possibly escalate privileges if kernel symlink restrictions were disabled.
