"Updated vdsm packages that fix one security issue and various bugs are
now available.

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.

VDSM is a management module that serves as a Red Hat Enterprise
Virtualization Manager agent on Red Hat Enterprise Virtualization
Hypervisor or Red Hat Enterprise Linux hosts.

A flaw was found in the way unexpected fields in guestInfo
dictionaries were processed. A privileged guest user could potentially
use this flaw to make the host the guest is running on unavailable to
the management server. (CVE-2013-0167)

The CVE-2013-0167 issue was discovered by Dan Kenigsberg of the Red
Hat Enterprise Virtualization team.

This update also fixes various bugs. Refer to the Technical Notes for
information about these changes :

https://access.redhat.com/site/documentation/en-US/
Red_Hat_Enterprise_Virtualization/3.2/html/Technical_Notes/
chap-RHSA-2013-0886.html

All users managing Red Hat Enterprise Linux Virtualization hosts using
Red Hat Enterprise Virtualization Manager are advised to install these
updated packages, which fix these issues.

These updated packages will be provided to users of Red Hat Enterprise
Virtualization Hypervisor in the next rhev-hypervisor6 errata package."
