Synopsis
========
Data validation in KDE Systemsettings could lead to local privilege
escalation.
Background
==========
KDE workspace configuration module for setting the date and time has a
helper program
which runs as root for performing actions.

Package / Vulnerable / Unaffected

1 kde-base/systemsettings < 4.11.13-r1 >= 4.11.13-r1
Description
===========
KDE Systemsettings fails to properly validate user input before passing
it as argument in context of higher privilege.
Impact

utility name) argument.
Workaround

Add a polkit rule to disable the org.kde.kcontrol.kcmclock.save action.
