Detail
| Problem Description: Updated openstack-nova packages that fix one security issue, several bugs, and add various enhancements are now available for Red Hat Enterprise Linux OpenStack Platform 4.0. Red Hat Product Security 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. 2. Relevant releases/architectures: Red Hat Enterprise Linux OpenStack Platform 4.0 - noarch 3. Description: 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. 4. Solution: Before applying this update, make sure all previously released errata relevant to your system have been applied. This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/articles/11258 5. Bugs fixed (https://bugzilla.redhat.com/): 1083625 - Some operations broken during live upgrade from Havana to Icehouse 1098312 - FC cinder volumes still show mpath device on nova host after volumes are detached from instance. 1146086 - Rebase openstack-nova to 2013.2.4 1152346 - CVE-2014-8750 openstack-nova: Nova VMware driver may connect VNC to another tenant's console |
