Advisory ID:       RHSA-2022:1930-01
Product:           Red Hat Enterprise Linux
Advisory URL:      https://access.redhat.com/errata/RHSA-2022:1930

=====================================================================

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
of Moderate. 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.

2. Relevant releases/architectures:

Red Hat Enterprise Linux AppStream (v. 8) - aarch64, ppc64le, s390x, x86_64

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: dbus access control bypass (CVE-2021-44225)
