An update for kdelibs is now available for Red Hat Enterprise Linux 7

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.

Summary

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.
