"From Red Hat Security Advisory 2017:1264 :

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

Red Hat Product Security has rated this update as having a security
impact of Important. A Common Vulnerability Scoring System (CVSS) base
score, which gives a detailed severity rating, is available for each
vulnerability from the CVE link(s) in the References section.

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."
