Severity:	high
Title:	KDE Plasma Workspaces: Privilege Escalation
Date:	07/06/2024
Bugs:	#933342
ID:	202407-20

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	Architecture(s)
kde-plasma/plasma-workspace	< 5.27.11.1	>= 5.27.11.1	All supported architectures

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"
