(RHSA-2015:0790) Important: openstack-nova security, bug fix, and enhancement update

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 and
controlling access through users and projects.

It was discovered that the OpenStack Compute (nova) console websocket did
not correctly verify the origin header. An attacker could use this flaw to
conduct a cross-site websocket hijack attack. Note that only Compute setups
with VNC or SPICE enabled were affected by this flaw. (CVE-2015-0259)

Red Hat would like to thank the OpenStack project for reporting this issue.
Upstream acknowledges Brian Manifold of Cisco, and Paul McMillan of Nebula
as the original reporters.

In addition to the above issue, this update also addresses bugs and
enhancements which are documented in the Red Hat Enterprise Linux OpenStack
Platform Technical Notes, linked to in the References section.

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