RHEL 6 : openstack-nova (RHSA-2014:1689)

critical Nessus Plugin ID 210174

Synopsis

The remote Red Hat host is missing a security update.

Description

The remote Redhat Enterprise Linux 6 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2014:1689 advisory.

OpenStack Compute (nova) launches and schedules large networks of virtual machines, creating a redundant and scalable cloud computing platform.
Compute provides the software, control panels, and APIs required to orchestrate a cloud, including running virtual machine instances, managing networks, and controlling access through users and projects.

A race condition flaw was found in the way the nova VMware driver handled VNC port allocation. An authenticated user could use this flaw to gain unauthorized console access to instances belonging to other tenants by repeatedly spawning new instances. Note that only nova setups using the VMware driver and the VNC proxy service were affected. (CVE-2014-8750)

The openstack-nova packages have been upgraded to upstream version 2013.2.4, which provides a number of bug fixes and enhancements over the previous version. (BZ#1146086)

This update also fixes the following bug:

* Prior to this update, certain RPC messages were not sending the correct data format when the version cap was set. During a live upgrade from Red Hat Enterprise Linux OpenStack Platform 4.0 to Red Hat Enterprise Linux OpenStack Platform 5.0, when there were Compute nodes running different versions of the code, some operations would fail on the Compute hosts that were not upgraded. With this update, proper version of the data is sent in all cases, and all RPC calls succeed during the live migration.
(BZ#1083625)

All openstack-nova users are advised to upgrade to these updated packages, which correct these issues and add these enhancements.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
