Synopsis :

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

Description :

Updated rhev-hypervisor packages that fix multiple security issues,
several bugs, and add various enhancements are now available.

Red Hat Product Security has rated this update as having 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-hypervisor 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 heap-based buffer overflow flaw was found in the way JasPer decoded
JPEG 2000 image files. A specially crafted file could cause an
application using JasPer to crash or, possibly, execute arbitrary
code. (CVE-2014-8138)

A race condition flaw, leading to a heap-based memory corruption, was
found in spice's worker_update_monitors_config() function, which runs
under the QEMU-KVM context on the host. A user in a guest could
leverage this flaw to crash the host QEMU-KVM process or, possibly,
execute arbitrary code with the privileges of the host QEMU-KVM
process. (CVE-2015-3247)

A double free flaw was found in the way JasPer parsed ICC color
profiles in JPEG 2000 image files. A specially crafted file could
cause an application using JasPer to crash or, possibly, execute
arbitrary code. (CVE-2014-8137)

It was found that the idle timeout in the Red Hat Enterprise
Virtualization Manager Web Admin interface failed to log out a session
if a VM has been selected in the VM grid view. This could allow a
local attacker to access the web interface if it was left unattended.
(CVE-2015-1841)

Red Hat would like to thank oCERT for reporting CVE-2014-8137 and
CVE-2014-8138. oCERT acknowledges Jose Duart of the Google Security
Team as the original reporter. The CVE-2015-3247 issue was discovered
by Frediano Ziglio of Red Hat. The CVE-2015-1841 issue was discovered
by Einav Cohen of Red Hat.

This update also fixes the following bug :

* Previously, installing the Red Hat Enterprise Virtualization
Hypervisor 7 RPM on a Red Hat Enterprise Linux 6 host failed, because
no such thing was available. Now, the Red Hat Enterprise
Virtualization Hypervisor 7 RPM is available in the
rhel-6-server-rhevh-rpms channel, and can be installed on a Red Hat
Enterprise Linux 6 host. (BZ#1193678)

In addition, this update adds the following enhancement :

* With this release, the Red Hat Enterprise Virtualizaton Hypervisor
now includes the drivers for the Dell Shared PERC8 RAID Controller.
(BZ#1186582)

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