The MOTD update script in the base-files package in Ubuntu 18.04 LTS prior to 10.1ubuntu2.2, and Ubuntu 18.10 prior to 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.
