a security issue in KDE which under Ubuntu and some other distros
allows a program to run arbitrary processes as root from an admin user
without any prompts.

kde-workspace < 4.14.3

KDE workspace configuration module for setting the date and time has a
helper program which runs as root for performing actions. This is
secured with polkit.

This helper takes the name of the ntp utility to run as an argument.
This allows a hacker to run any arbitrary command as root under the
guise of updating the time.

https://git.reviewboard.kde.org/r/120977/

Do not pass ntpUtility as an argument to datetime helper
 
Passing the name of a binary to run to a polkit helper is a security
risk as it allows any arbitrary process to be executed.

Use CVE-2014-8651.
