http://security.gentoo.org/

Severity:	normal
Title:	KDE Systemsettings: Privilege escalation
Date:	12/30/2015
Bugs:	#528468
ID:	201512-12

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	Architecture(s)
kde-base/systemsettings	< 4.11.13-r1	>= 4.11.13-r1	All supported architectures

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 --verbose
      ">=kde-base/systemsettings-4.11.13-r1"
