(RHSA-2014:1168) Important: rhev-hypervisor6 security and bug fix update

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 NULL pointer dereference flaw was found in the way the Linux kernel’s
networking implementation handled logging while processing certain invalid
packets coming in via a VxLAN interface. A remote attacker could use this
flaw to crash the system by sending a specially crafted packet to such an
interface. (CVE-2014-3535)

Two integer overflow flaws were found in the QEMU block driver for QCOW
version 1 disk images. A user able to alter the QEMU disk image files
loaded by a guest could use either of these flaws to corrupt QEMU process
memory on the host, which could potentially result in arbitrary code
execution on the host with the privileges of the QEMU process.
(CVE-2014-0222, CVE-2014-0223)

Red Hat would like to thank NSA for reporting CVE-2014-0222 and
CVE-2014-0223.

This update also fixes the following bug:

• Previously, an updated version of Qlogic firmware was not supported in
  the Red Hat Enterprise Virtualization Hypervisor 6.5 image and an error
  message returned when users were using a newer version of Qlogic firmware.
  This update includes the latest Qlogic firmware package in the Red Hat
  Enterprise Virtualization Hypervisor 6.5 image so no firmware errors are
  returned. (BZ#1135780)

This updated package also 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-2012-6647, CVE-2013-7339, CVE-2014-2672, CVE-2014-2678, CVE-2014-2706,
CVE-2014-2851, CVE-2014-3144, CVE-2014-3145, CVE-2014-0205, CVE-2014-3917,
and CVE-2014-4667 (kernel issues)

Users of the Red Hat Enterprise Virtualization Hypervisor are advised to
upgrade to this updated package.
