3. Description:

Red Hat Enterprise Virtualization Manager is a visual tool for centrally
managing collections of virtual servers running Red Hat Enterprise Linux
and Microsoft Windows. This package also includes the Red Hat Enterprise
Virtualization Manager API, a set of scriptable commands that give
administrators the ability to perform queries and operations on Red Hat
Enterprise Virtualization Manager.

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

It was discovered that, when loading XML/RSDL documents, the oVirt Engine
back end module used an insecure DocumentBuilderFactory. A remote,
authenticated attacker could use this flaw to read files accessible to the
user running the ovirt-engine server, and potentially perform other more
advanced XML External Entity (XXE) attacks. (CVE-2014-3573)
