Red Hat Enterprise Virtualization Hypervisor Bugs Let Remote Users Execute Arbitrary Code, Gain Elevated Privileges, and Deny Service
SecurityTracker Alert ID:  1033459
SecurityTracker URL:  http://securitytracker.com/id/1033459
CVE Reference:   CVE-2014-8137, CVE-2014-8138, CVE-2015-1841, CVE-2015-3247   (Links to External Site)
Date:  Sep 3 2015
Impact:   Denial of service via network, Execution of arbitrary code via network, Root access via local system, User access via local system, User access via network
Fix Available:  Yes  Vendor Confirmed:  Yes  

Description:   Several vulnerabilities were reported in Red Hat Enterprise Virtualization Hypervisor. A remote user can cause arbitrary code to be executed on the target user's system. A local user on the guest system can cause denial of service conditions or gain elevated privileges on the host system. A local user can access the target system.

A remote user can create a JPEG 2000 image file with a specially crafted ICC color profile that, when loaded by the target user via JasPer, will trigger a double-free memory error and execute arbitrary code on the target system [CVE-2014-8137].

Jose Duart of the Google Security Team (via oCERT) reported this vulnerability.

A remote user can create a specially crafted JPEG 2000 image file that, when loaded by the target user via JasPer, will trigger a heap overflow and execute arbitrary code on the target system [CVE-2014-8138].

Jose Duart of the Google Security Team (via oCERT) reported this vulnerability.

A remote authenticated user on a guest system can exploit a race condition to trigger a memory corruption flaw in the worker_update_monitors_config() function to cause the host QEMU-KVM process to crash or execute arbitrary code [CVE-2015-3247].

Frediano Ziglio of Red Hat reported this vulnerability.

The Virtualization Manager web admin interface does not properly time out a session when a virtual machine (VM) is selected in the VM grid view. A local user can potentially access an unattended web interface [CVE-2015-1841].

Einav Cohen of Red Hat reported this vulnerability.

Impact:   A remote user can create content that, when loaded by the target user, will execute arbitrary code on the target user's system.

A local user on the guest system can cause denial of service conditions on the host system.

A local user on the guest system can gain elevated privileges on the host system.

A local user can access the target system.

Solution:   Red Hat has issued a fix.

                   Red Hat Security Advisory

Synopsis:          Important: rhev-hypervisor security, bug fix, and enhancement update
Advisory ID:       RHSA-2015:1713-01
Product:           Red Hat Enterprise Virtualization
Advisory URL:      https://rhn.redhat.com/errata/RHSA-2015-1713.html
Issue date:        2015-09-03
CVE Names:         CVE-2014-8137 CVE-2014-8138 CVE-2015-1841 
                   CVE-2015-3247 
=====================================================================

1. Summary:

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.

2. Relevant releases/architectures:

RHEL 7-based RHEV-H - noarch
RHEV Hypervisor for RHEL-6 - noarch

3. Description:

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.

4. Solution:

Before applying this update, make sure all previously released errata
relevant to your system have been applied.
