                   Red Hat Security Advisory

Synopsis:          Moderate: Red Hat Virtualization security, bug fix, and enhancement update
Advisory ID:       RHSA-2018:2079-01
Product:           Red Hat Virtualization
Advisory URL:      https://access.redhat.com/errata/RHSA-2018:2079
Issue date:        2018-06-27
CVE Names:         CVE-2018-10855 
=====================================================================

1. Summary:

Updated redhat-virtualization-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:

RHEL 7-based RHEV-H for RHEV 4 (build requirements) - noarch, x86_64
Red Hat Virtualization 4 Hypervisor for RHEL 7 - noarch

3. Description:

The redhat-virtualization-host packages provide the Red Hat Virtualization
Host. These packages include redhat-release-virtualization-host,
ovirt-node, and rhev-hypervisor. Red Hat Virtualization Hosts (RHVH) are
installed using a special build of Red Hat Enterprise Linux with only the
packages required to host virtual machines. RHVH features a Cockpit user
interface for monitoring the host's resources and performing administrative
tasks.

The ovirt-node-ng packages provide the Red Hat Virtualization Host. These
packages include redhat-release-virtualization-host, ovirt-node, and
rhev-hypervisor. Red Hat Virtualization Hosts (RHVH) are installed using a
special build of Red Hat Enterprise Linux with only the packages required
to host virtual machines. RHVH features a Cockpit user interface for
monitoring the host's resources and performing administrative tasks.

The following packages have been upgraded to a later upstream version:
imgbased (1.0.20), redhat-release-virtualization-host (4.2),
redhat-virtualization-host (4.2). (BZ#1590664)

Security Fix(es):

* ansible: Failed tasks do not honour no_log option allowing for secrets to
be disclosed in logs (CVE-2018-10855)

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.

Red Hat would like to thank Tobias Henkel (BMW Car IT GmbH) for reporting
this issue.

Bug Fix(es):

* Previously, if systems were configured to skip Logical Volume Manager
(LVM) clusters, imgbased sees output that is unrelated to the Logical
Volumes that are being queried.

As a result, imgbased failed to parse the output, causing Red Hat
Virtualization Host updates to fail.

In this release imgbased now ignores output from skipped clusters enabling
imgbased LVM commands to return successfully. (BZ#1568414)

Enhancement(s):

* Starting from version 4.0, Red Hat Virtualization Hosts could not be
deployed from Satellite, and therefore could not take advantage of
Satellite's tooling features.

In this release, Red Hat Virtualization Hosts can now be deployed from
Satellite 6.3.2 and later. (BZ#1484532)

4. Solution:

For details on how to apply this update, which includes the changes
described in this advisory, refer to:

https://access.redhat.com/articles/2974891

5. Bugs fixed (https://bugzilla.redhat.com/):

1484532 - [RFE] Deployment via Satellite
1534197 - After updating to current RHV-H, vdsmd consistently fails to start on startup.
1568414 - missing lvm filter causing "nodectl check" to fail to verify thinprovisioned local lv metadata
1588855 - CVE-2018-10855 ansible: Failed tasks do not honour no_log option allowing for secrets to be disclosed in logs
