Synopsis :

The remote Red Hat host is missing a security update.

Description :

An updated rhev-hypervisor6 package that fixes multiple security
issues and various bugs is now available.

The Red Hat Security Response Team has rated this update as having
moderate security impact. Common Vulnerability Scoring System (CVSS)
base scores, which give detailed severity ratings, are available for
each vulnerability from the CVE links 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.

Multiple errors in glibc's formatted printing functionality could
allow an attacker to bypass FORTIFY_SOURCE protections and execute
arbitrary code using a format string flaw in an application, even
though these protections are expected to limit the impact of such
flaws to an application abort. (CVE-2012-3404, CVE-2012-3405,
CVE-2012-3406)

This updated package provides updated components that include fixes
for various security issues. These issues have no security impact on
Red Hat Enterprise Virtualization Hypervisor itself, however. The
security fixes included in this update address the following CVE
numbers :

CVE-2012-3817 (bind issue)

CVE-2012-3571 and CVE-2012-3954 (dhcp issues)
