(RHSA-2015:0888) Moderate: Red Hat Enterprise Virtualization Manager 3.5.1 update

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
(API).

It was discovered that the permissions to allow or deny snapshot creation
were ignored during live storage migration of a VM’s disk between storage
domains. An attacker able to live migrate a disk between storage domains
could use this flaw to cause a denial of service. (CVE-2015-0237)

It was discovered that a directory shared between the ovirt-engine-dwhd
service and a plug-in used during the service’s startup had incorrect
permissions. A local user could use this flaw to access files in this
directory, which could potentially contain sensitive information.
(CVE-2015-0257)

The CVE-2015-0237 issue was discovered by Red Hat Enterprise Visualization
Engineering, and the CVE-2015-0257 issue was discovered by Yedidyah Bar
David of the Red Hat Enterprise Virtualization team.
