RHEL 6 : rhev-hypervisor (RHSA-2015:1713)

High Nessus Plugin ID 85999

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.

Solution

Update the affected rhev-hypervisor6 and / or rhev-hypervisor7 packages.
