Synopsis :

The remote Red Hat host is missing a security update.

Description :

An updated rhev-hypervisor6 package that fixes one security issue,
various bugs, and adds enhancements is now available.

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.

The rhev-hypervisor6 package provides a Red Hat Enterprise
Virtualization Hypervisor ISO disk image. The Red Hat Enterprise
Virtualization Hypervisor is a dedicated Kernel-based Virtual Machine
(KVM) hypervisor. It includes everything necessary to run and manage
virtual machines: A subset of the Red Hat Enterprise Linux operating
environment and the Red Hat Enterprise Virtualization Agent.

Note: Red Hat Enterprise Virtualization Hypervisor is only available
for the Intel 64 and AMD64 architectures with virtualization
extensions.

A flaw was found in the way Red Hat Enterprise Virtualization
Hypervisor hosts were added to the Red Hat Enterprise Virtualization
environment. The Python scripts needed to configure the host for Red
Hat Enterprise Virtualization were downloaded in an insecure way, that
is, without properly validating SSL certificates during HTTPS
connections. An attacker on the local network could use this flaw to
conduct a man-in-the-middle attack, potentially gaining root access to
the host being added to the Red Hat Enterprise Virtualization
environment. This update provides the VDSM part of the fix. The
RHSA-2012:1506 Red Hat Enterprise Virtualization Manager update must
also be installed to completely fix this issue. (CVE-2012-0861)

The CVE-2012-0861 issue was discovered by Red Hat.

Enterprise Virtualization Hypervisor itself, however. The security fix
