RHEL 8 : Red Hat Virtualization Host security update [ovirt-4.4.8] (Moderate) (RHSA-2021:3459)

high Nessus Plugin ID 165119

Language:

Synopsis

The remote Red Hat host is missing one or more security updates for Red Hat Virtualization Host.

Description

The remote Redhat Enterprise Linux 8 host has a package installed that is affected by multiple vulnerabilities as referenced in the RHSA-2021:3459 advisory.

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)

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the RHEL Red Hat Virtualization Host package based on the guidance in RHSA-2021:3459.
