Red Hat Security Advisory

Synopsis: Important: rhvm-setup-plugins security, bug fix, and
enhancement update
Advisory ID: RHSA-2018:2328-01
Product: Red Hat Virtualization
Advisory URL: https://access.redhat.com/errata/RHSA-2018:2328
Issue date: 2018-07-31
CVE Names: CVE-2018-3639
=====================================================================

1. Summary:

An update for rhvm-setup-plugins is now available for Red Hat
Virtualization Engine 4.2.

Red Hat Product Security has rated this update as having a security impact
of Important. 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:

RHV-M 4.2 - noarch

3. Description:

The rhvm-setup-plugins package adds functionality exclusive only to Red Hat
Virtualization Manager, and is not available for the upstream ovirt-engine.
It includes the configuration of the Red Hat Support plugin, copying
downstream-only artifacts to the ISO domain, and links to the knowledgebase
and other support material.

The following packages have been upgraded to a later upstream version:
rhvm-setup-plugins (4.2.10). (BZ#1596152)

Security Fix(es):

* An industry-wide issue was found in the way many modern microprocessor
designs have implemented speculative execution of Load & Store instructions
(a commonly used performance optimization). It relies on the presence of a
precisely-defined instruction sequence in the privileged code as well as
the fact that memory read from address to which a recent memory write has
occurred may see an older value and subsequently cause an update into the
microprocessor's data cache even for speculatively executed instructions
that never actually commit (retire). As a result, an unprivileged attacker
could use this flaw to read privileged memory by conducting targeted cache
side-channel attacks. (CVE-2018-3639, x86 AMD)

Red Hat would like to thank Ken Johnson (Microsoft Security Response
Center) and Jann Horn (Google Project Zero) for reporting this issue.

Bug Fix(es):

* This update adds support for IBM POWER9 hypervisors with RHEL-ALT and
POWER9 guests. It also adds support for POWER8 guests on a POWER9
hypervisor and live migration of POWER8 guests between POWER8 and POWER9
hypervisors. (BZ#1592320)
