Type: Security Advisory

Details

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

The Red Hat Security Response Team has rated this update as having
important 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-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.

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-2013-4162 and CVE-2013-4299 (kernel issues)

CVE-2013-4296 and CVE-2013-4311 (libvirt issues)
