Description

Red Hat Enterprise Virtualization Manager 3.5.1 is now available.

Red Hat Product Security has rated this update as having Moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

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.

These updated Red Hat Enterprise Virtualization Manager packages also include numerous bug fixes and various enhancements. Space precludes documenting all of these changes in this advisory. Users are directed to the Red Hat Enterprise Virtualization 3.5 Technical Notes, linked to in the References, for information on the most significant of these changes.

All Red Hat Enterprise Virtualization Manager users are advised to upgrade to these updated packages, which resolve these issues and add these enhancements.
