Synopsis:          Moderate: RHV RHEL Host (ovirt-host) 4.4.z [ovirt-4.4.5] security, bug fix, enhancement
Advisory ID:       RHSA-2021:1184-01
Product:           Red Hat Virtualization
Advisory URL:      https://access.redhat.com/errata/RHSA-2021:1184
Issue date:        2021-04-14
CVE Names:         CVE-2020-28458 
=====================================================================

1. Summary:

Updated host packages that fix several bugs and add various enhancements
are now available.

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 Virtualization 4 Hypervisor for RHEL 8 - noarch, x86_64
Red Hat Virtualization 4 Management Agent for RHEL 7 Hosts - noarch, ppc64le, x86_64

3. Description:

The ovirt-hosted-engine-setup package provides a self-hosted engine tool
for the Red Hat Virtualization Manager. A self-hosted engine is a
virtualized environment in which the Manager runs on a virtual machine on
the hosts managed by the Manager.
Bug Fix(es):

* In this release, it is now possible to enter a path to the OVA archive
for local appliance installation using the cockpit-ovirt UI. (BZ#1755156)

* Previously, following a successful migration on the Self-hosted Engine,
he HA agent on the source host immediately moved to the state EngineDown,
and shorly thereafter tried to start the engine locally, if the destination
host didn't update the shared storage quickly enough, marking the Manager
virtual machine as being up.
As a result, starting the virtual machine failed due to a shared lock held
by the destination host. This also resulted in generating false alarms and
notifications.
In this release, the HA agent first moves to the state EngineMaybeAway,
providing the destination host more time to update the shared storage with
the updated state. As a result, no notifications or false alarms are
generated. 
Note: in scenarios where the virtual machine needs to be started on the
source host, this fix slightly increases the time it takes the Manager
virtual
machine on the source host to start. (BZ#1815589)

* Previously, if a host in the Self-hosted Engine had an ID number higher
than 64, other hosts did not recognize that host, and the host did not
appear in 'hosted-engine --vm-status'.
In this release, the Self-hosted Engine allows host ID numbers of up to
2000. (BZ#1916032)

* ovirt-hosted-engine-setup now requires ansible-2.9.17. (BZ#1921108)

* Previously the logical names for disks without a mounted filesystem were
not displayed in the Red Hat Virtualization Manager. 
In this release, logical names for such disks are properly reported
provided the version of QEMU Guest Agent in the virtual machine is 5.2 or
higher. (BZ#1836661)

* Previously, if the Seal option was used when creating a template for
Linux virtual machines, the original host name was not removed from the
template. 
In this release, the host name is set to localhost or the new virtual
machine host name. (BZ#1860492)

* Previously, the used memory of the host didn't take the SReclaimable
memory into consideration while it did for free memory. As a result, there
were discrepancies in the host statistics. 
In this release, the SReclaimable memory is a part of the used memory
calculation. (BZ#1916519)

Security Fix(es):

* datatables.net: prototype pollution if 'constructor' were used in a data
property name (CVE-2020-28458)
