Red Hat Enterprise Virtualization Manager 2.2.4 is now available for Red
Hat Enterprise Virtualization.

The Red Hat Security Response Team has rated this update as having
important security impact. A Common Vulnerability Scoring System (CVSS)
base score, which gives a detailed severity rating, is available from the
CVE link 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 Simple Protocol for Independent Computing Environments (SPICE) is a
remote display protocol.

A race condition was found in the way the SPICE plug-in for Microsoft
Internet Explorer and the SPICE client communicated. A local attacker could
use this flaw to trick the plug-in and the SPICE client into communicating
over an attacker-controlled named pipe, possibly gaining access to
authentication details, or resulting in privilege escalation.

This updated Red Hat Enterprise Virtualization Manager package also fixes
several bugs. Documentation for these bug fixes will be available shortly

All Red Hat Enterprise Virtualization Manager users are advised to install
this updated package, which corrects this issue and fixes the bugs noted in
the Technical Notes document, linked to in the References.
