1. Summary:

An update for org.ovirt.engine-root is now available for RHEV Engine
version 4.0.

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:

RHEV-M 4.0 - noarch

3. Description:

The Red Hat Virtualization Manager is a centralized management platform
that allows system administrators to view and manage virtual machines. The
Manager provides a comprehensive range of features including search
capabilities, resource management, live migrations, and virtual
infrastructure provisioning.

The Manager is a JBoss Application Server application that provides several
interfaces through which the virtual environment can be accessed and
interacted with, including an Administration Portal, a User Portal, and a
Representational State Transfer (REST) Application Programming Interface

Security Fix(es):

* It was found that the ovirt-engine-provisiondb utility did not correctly
sanitize the authentication details used with the "--provision*db" options
from the output before storing them in log files. This could allow an
attacker with read access to these log files to obtain sensitive
information such as passwords. (CVE-2016-5432)

This issue was discovered by Yedidyah Bar David (Red Hat).

Bug Fix(es):

* Previously, when checking permissions for a CPU profile, group
permissions were not considered. Users that were part of a group could not
assign a CPU profile and so could not start a virtual machine. This was
fixed by using PermissionDao and correct SQL functions when checking
permissions, so group permissions are now considered. (BZ#1371888)

* Setting only one of the thresholds for power saving/evenly distributed
memory based balancing (high or low) can lead to unexpected results. For
example, when in power saving load balancing the threshold for memory over
utilized hosts was set with a value, and the threshold for memory under
utilized hosts was undefined thus getting a default value of 0. All hosts
were considered as under utilized hosts and were chosen as sources for
migration, but no host was chosen as a destination for migration.

This has now been changed so that when the threshold for memory under
utilized host is undefined, it gets a default value of Long.MAX. Now, when
the threshold for memory over utilized hosts is set with a value, and the
threshold for memory under utilized host is undefined, only over utilized
hosts will be selected as sources for migration, and destination hosts will
be hosts that are not over utilized. (BZ#1354281)

* This update ensures that Quality of Service (QoS) Storage values that are
sent to the VDSM service, are used by the VDSM and Memory Overcommit
Manager (MoM). The result is that QoS is live-applied on virtual machines,
and all MoM-related virtual machine changes are only applied when the
memory ballooning device is enabled on the virtual machine. (BZ#1328731)


* Previously, it was possible to install incorrect versions of virtio
drivers, especially when running an older Windows operating system. This
sometimes caused the guest to terminate unexpectedly with a stop error,
also known as the "Blue Screen of Death", if the particular driver and
Windows versions were incompatible. This update adds target OS version
information to driver files, which enables Windows to automatically select
the best driver when pointed to the root of the virtio-win CD image.
Installing an incompatible driver version manually is also no longer
possible, as Windows now presents the user with an error message if
installation is attempted. (BZ#1328181)

* With this release, Red Hat Virtualization now supports CephFS as a POSIX
storage domain. (BZ#1095615)
