Upgrade Ubuntu:16.04 kinit to version 5.18.0-0ubuntu1.1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream kinit package and not the kinit package as distributed by Ubuntu.
See How to fix? for Ubuntu:16.04 relevant fixed versions and status.
kinit in KDE Frameworks before 5.23.0 uses weak permissions (644) for /tmp/xauth-xxx-_y, which allows local users to obtain X11 cookies of other users and consequently capture keystrokes and possibly gain privileges by reading the file.
