Synopsis :

The remote Red Hat host is missing one or more security updates.

Description :

An updated rhev-hypervisor5 package that fixes one security issue and
various bugs is 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.

The rhev-hypervisor5 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.

It was discovered that the formatted printing functionality in glibc
did not properly restrict the use of alloca(). This 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-2012-3406)

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 (dhcp issue)

CVE-2012-2313 (kernel issue)

CVE-2012-0441 (nss issue)

CVE-2012-2337 and CVE-2012-3440 (sudo issues)
