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):

* A flaw was found in RHEV Manager, where it wrote sensitive data to the
engine-setup log file. A local attacker could exploit this flaw to view
sensitive information such as encryption keys and certificates (which could
then be used to steal other sensitive information such as passwords).

This issue was discovered by Simone Tiraboschi (Red Hat).

Bug Fix(es):

* With this update, users are now warned to set the system in global
maintenance mode before running the engine-setup command. This is because
data corruption may occur if the engine-setup command is run without
setting the system into global maintenance mode. This update means that the
user is warned and the setup will be aborted if the system is not in global
maintenance mode and the engine is running in the hosted engine
configuration. (BZ#1359844)

* Previously, the update of the compatibility version of a cluster with
many running virtual machines that are installed with the guest-agent
caused a deadlock that caused the update to fail. In some cases, these
clusters could not be upgraded to a newer compatibility version. Now, the
deadlock in the database has been prevented so that a cluster with many
running virtual machines that are installed with the guest-agent can be
upgraded to newer compatibility version. (BZ#1369415)

* Previously, a virtual machine with a null CPU profile id stored in the
database caused a NPE when editing the virtual machine. Now, a virtual
machine with a null CPU profile id stored in the database is correctly
handled and the virtual machine can be edited. (BZ#1373090)

* 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#1359767)

* Previously, recently added logs that printed the amount of virtual
machines running on a host were excessively written to the log file. Now,
the frequency of these log have been reduced by printing them only upon a
change in the number of virtual machines running on the host. (BZ#1367519)
