Red Hat Security Advisory 2019-2285-01 - 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 kernel module providing layer-4 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 to achieve high availability with director failover. An improper path name validation was addressed.
