1. Summary:

An update for cockpit-ovirt, ovirt-host, ovirt-hosted-engine-ha,
ovirt-hosted-engine-setup, and vdsm is now available for Red Hat
Virtualization 4 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 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 VDSM service is required by a Virtualization Manager to manage the
Linux hosts. VDSM manages and monitors the host's storage, memory and
networks as well as virtual machine creation, other host administration
tasks, statistics gathering, and log collection.

Security Fix(es):

* nodejs-lodash: command injection via template (CVE-2021-23337)

* nodejs-lodash: ReDoS via the toNumber, trim and trimEnd functions
(CVE-2020-28500)

For more details about the security issue(s), including the impact, a CVSS
score, and other related information, refer to the CVE page(s) listed in
the References section.

Bug Fix(es):

* An update in libvirt has changed the way block threshold events are
submitted.
As a result, the VDSM was confused by the libvirt event, and tried to look
up a drive, logging a warning about a missing drive.
In this release, the VDSM has been adapted to handle the new libvirt
behavior, and does not log warnings about missing drives. (BZ#1948177)

* Previously, when a virtual machine was powered off on the source host of
a live migration and the migration finished successfully at the same time,
the two events  interfered with each other, and sometimes prevented
migration cleanup resulting in additional migrations from the host being
blocked. 
In this release, additional migrations are not blocked. (BZ#1959436)

* Previously, when failing to execute a snapshot and re-executing it later,
the second try would fail due to using the previous execution data. In this
release, this data will be used only when needed, in recovery mode.
(BZ#1984209)
