"From Red Hat Security Advisory 2019:1279 :

An update for pacemaker is now available for Red Hat Enterprise Linux
8.

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 Pacemaker cluster resource manager is a collection of technologies
working together to maintain data integrity and application
availability in the event of failures.

Security Fix(es) :

* pacemaker: Insufficient local IPC client-server authentication on
the client's side can lead to local privesc (CVE-2018-16877)

* pacemaker: Insufficient verification inflicted preference of
uncontrolled processes can lead to DoS (CVE-2018-16878)

* pacemaker: Information disclosure through use-after-free
(CVE-2019-3885)

For more details about the security issue(s), including the impact, a
CVSS score, acknowledgments, and other related information, refer to
the CVE page(s) listed in the References section.

Bug Fix(es) :

* Interrupted live migration will get full start rather than completed
migration (BZ#1695247)"
