Synopsis
========

A vulnerability has been discovered in KDE Plasma Workspaces, which can
lead to privilege escalation.

Background
==========

KDE Plasma workspace is a widget based desktop environment designed to
be fast and efficient.

Affected packages
=================

Package                      Vulnerable    Unaffected
---------------------------  ------------  ------------
kde-plasma/plasma-workspace  < 5.27.11.1   >= 5.27.11.1

Description
===========

Multiple vulnerabilities have been discovered in KDE Plasma Workspaces.
Please review the CVE identifiers referenced below for details.

Impact
======

KSmserver, KDE's XSMP manager, incorrectly allows connections via ICE
based purely on the host, allowing all local connections. This allows
another user on the same machine to gain access to the session
manager.

A well crafted client could use the session restore feature to execute
arbitrary code as the user on the next boot.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All KDE Plasma Workspaces users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=kde-plasma/plasma-workspace-5.27.11.1"
