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.

All KDE Systemsettings users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot -v ">=kde-base/systemsettings-4.11.13-r1"
