KDE Plasma Workspaces: Privilege Escalation — GLSA 202407-20

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

Affected packages

Package	kde-plasma/plasma-workspace on all architectures
Affected versions	< 5.27.11.1
Unaffected versions	>= 5.27.11.1

Background

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

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"
