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"
