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.

Affected packages
================
    -------------------------------------------------------------------
     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
=====
A local attacker could gain privileges via a crafted ntpUtility (ntp
utility name) argument.

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

Resolution
=========
All KDE Systemsettings users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot -v ">=kde-base/systemsettings-4.11.13-r1"
