Advisory URL:      https://rhn.redhat.com/errata/RHSA-2010-0478.html

=====================================================================

1. Summary:

Red Hat Enterprise Virtualization Manager 2.2 is now available for Red Hat
Enterprise Virtualization.

The Red Hat Security Response Team has rated this update as having moderate
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. Major changes in version 2.2 include an
import and export capability, and desktop support (VDI).

It was found that Red Hat Enterprise Virtualization Manager did not
correctly pass the postzero parameter for deleted volumes after snapshot
merging. This resulted in such volumes not being securely deleted as
expected. A guest user in a new, raw virtual machine (VM), created in a
data domain that has had VMs deleted from it, could use this flaw to read
limited data from those deleted VMs, potentially disclosing sensitive
information. (CVE-2010-2224)
