Synopsis
=======
A vulnerability has been discovered in SDDM which can lead to privilege
escalation.
Background
=========
SDDM is a modern display manager for X11 and Wayland sessions aiming to
be fast, simple and beautiful. It uses modern technologies like QtQuick,
which in turn gives the designer the ability to create smooth, animated
user interfaces.
Affected packages
================
Package Vulnerable Unaffected
------------- ------------ ------------
x11-misc/sddm < 0.18.1-r6 >= 0.18.1-r6
Description
==========
A vulnerability has been discovered in SDDM. Please review the CVE
identifier referenced below for details.
Impact
=====
SDDM passes the -auth and -displayfd command line arguments when
starting the Xserver. It then waits for the display number to be
received from the Xserver via the `displayfd`, before the Xauthority
file specified via the `-auth` parameter is actually written. This
results in a race condition, creating a time window in which no valid
Xauthority file is existing while the Xserver is already running.
The X.Org server, when encountering a non-existing, empty or
corrupt/incomplete Xauthority file, will grant any connecting client
access to the Xorg display. A local unprivileged attacker can thus
create an unauthorized connection to the Xserver and grab e.g. keyboard
input events from other legitimate users accessing the Xserver.
Workaround
=========
There is no known workaround at this time.
Resolution
=========
All SDDM users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=x11-misc/sddm-0.18.1-r6"
