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"
