Red Hat Security Advisory

Synopsis: Important: rhevm-setup-plugins security, bug fix, and enhancement update
Advisory ID: RHSA-2018:0052-01
Product: Red Hat Virtualization
Advisory URL: https://access.redhat.com/errata/RHSA-2018:0052
Issue date: 2018-01-05
=====================================================================

1. Summary:

An update for rhevm-setup-plugins is now available for RHEV Manager version
3.6.

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:

RHEV-M 3.6 ELS – noarch

3. Description:

The rhevm-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:
rhevm-setup-plugins (3.6.6). (BZ#1527109)

Security Fix(es):

* An industry-wide issue was found in the way many modern microprocessor
designs have implemented speculative execution of instructions (a commonly
used performance optimization). There are three primary variants of the
issue which differ in the way the speculative execution can be exploited.
Variant CVE-2017-5715 triggers the speculative execution by utilizing
branch target injection. It relies on the presence of a precisely-defined
instruction sequence in the privileged code as well as the fact that memory
accesses may cause allocation 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 cross the syscall
and guest/host boundaries and read privileged memory by conducting targeted
cache side-channel attacks. (CVE-2017-5715)

Note: This is the rhevm-setup-plugins side of the CVE-2017-5715 mitigation.

Red Hat would like to thank Google Project Zero for reporting this issue.
