Description

The Red Hat Enterprise Virtualization Manager is a centralized management
platform that allows system administrators to view and manage virtual
machines. The Red Hat Enterprise Virtualization 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
(API).

It was discovered that running the domain management tool with the validate
action ("rhevm-manage-domains -action=validate") logged administrative
passwords to a world-readable log file. A local attacker could use this
flaw to gain control of systems that are managed by Red Hat Enterprise
Virtualization Manager. (CVE-2012-6115)

A flaw was found in the way the MoveDisk command checked permissions on the
target storage domain. A privileged user (a storage admin of a storage
domain) could use this flaw to exhaust all available free space in another
storage domain they would otherwise not have access to. (CVE-2013-0168)

The CVE-2012-6115 issue was discovered by Andrew Cathrow of Red Hat. The
CVE-2013-0168 issue was discovered by Ondrej Machacek of Red Hat.

Previously, upgrading from Red Hat Enterprise Virtualization Manager 3.0 to
3.1 was not formally supported by Red Hat. This update fixes a number of
known issues with the upgrade process. As a result, upgrading from Red Hat
Enterprise Virtualization Manager 3.0 to 3.1 is now supported.

Manager 3.1, consult the Installation Guide:
