3. Description:
The K Desktop Environment (KDE) is a graphical desktop environment for the
X Window System. The kdelibs packages include core libraries for the K
Desktop Environment.
Security Fix(es):
* A privilege escalation flaw was found in the way kdelibs handled D-Bus
messages. A local user could potentially use this flaw to gain root
privileges by spoofing a callerID and leveraging a privileged helper
application. (CVE-2017-8422)
Red Hat would like to thank Sebastian Krahmer (SUSE) for reporting this
issue.
4. Solution:
For details on how to apply this update, which includes the changes
described in this advisory, refer to:
https://access.redhat.com/articles/11258
The desktop must be restarted (log out, then log back in) for this update
to take effect.
5. Bugs fixed (https://bugzilla.redhat.com/):
1449647 – CVE-2017-8422 kauth: service invoking dbus is not properly checked and allows local privilege escalation
