Synopsis :

The remote Red Hat host is missing a security update.

Description :

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

Important 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

It was discovered that GnuTLS did not correctly handle certain errors
that could occur during the verification of an X.509 certificate,
causing it to incorrectly report a successful verification. An
attacker could use this flaw to create a specially crafted certificate
that could be accepted by GnuTLS as valid for a site chosen by the
attacker. (CVE-2014-0092)

A flaw was found in the way the get_rx_bufs() function in the
vhost_net implementation in the Linux kernel handled error conditions
reported by the vhost_get_vq_desc() function. A privileged guest user
could use this flaw to crash the host. (CVE-2014-0055)

A heap-based buffer overflow flaw was found in the Linux kernel's
cdc-wdm driver, used for USB CDC WCM device management. An attacker
with physical access to a system could use this flaw to cause a denial
of service or, potentially, escalate their privileges. (CVE-2013-1860)

The CVE-2014-0092 issue was discovered by Nikos Mavrogiannopoulos of
the Red Hat Security Technologies Team.

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-2014-0101, and CVE-2014-0069 (kernel issues)

CVE-2010-2596, CVE-2013-1960, CVE-2013-1961, CVE-2013-4231,
CVE-2013-4232, CVE-2013-4243, and CVE-2013-4244 (libtiff issues)

Users of the Red Hat Enterprise Virtualization Hypervisor are advised
to upgrade to this updated package, which corrects these issues.
