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
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.
