3. Description:

The Red Hat Enterprise 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
(API).

It was found that the ovirt-engine REST API resolved entities in XML API
calls. A remote attacker with credentials to call the ovirt-engine REST
API could use this flaw to read files accessible to the user running the
ovirt-engine JBoss server, and potentially perform other more advanced XXE
attacks. (CVE-2014-3485)

This issue was discovered by David Jorm of Red Hat Product Security.

All Red Hat Enterprise Virtualization Manager users are advised to upgrade
to these updated packages, which resolve this issue.
