Description :

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

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.

Upgrade Note: If you upgrade the Red Hat Enterprise Virtualization
Hypervisor through the 3.2 Manager administration portal, the Host may
appear with the status of 'Install Failed'. If this happens, place the
host into maintenance mode, then activate it again to get the host
back to an 'Up' state

A stack-based buffer overflow flaw was found in the way the
reds_handle_ticket() function in the spice-server library handled
decryption of ticket data provided by the client. A remote attacker
able to initiate a SPICE connection to the guest could use this flaw
to crash the guest. (CVE-2013-4282)

This issue was discovered by Tomas Jamrisko of Red Hat.
