1. Summary:

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

Red Hat Product Security has rated this update as having a security impact

3. Description:

The keepalived utility provides simple and robust facilities for load

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.
