An update for keepalived 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,

3. Description:
The keepalived utility provides simple and robust facilities for load
balancing and high availability. The load balancing framework relies on the
well-known and widely used IP Virtual Server (IPVS) kernel module providing
layer-4 (transport layer) load balancing. Keepalived implements a set of
checkers to dynamically and adaptively maintain and manage a load balanced
server pool according to the health of the servers. Keepalived also
implements the Virtual Router Redundancy Protocol (VRRPv2) to achieve high
availability with director failover.
Security Fix(es):
* keepalived: Heap-based buffer overflow when parsing HTTP status codes
allows for denial of service or possibly arbitrary code execution
(CVE-2018-19115)
