1. Summary:

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.

2. 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 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.
(CVE-2010-2793)

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