(RHSA-2016:0013) Moderate: openstack-nova security and bug fix 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 and controlling access through users and projects.

A vulnerability was discovered in the way OpenStack Compute (nova)
networking handled security group updates; changes were not applied to
already running VM instances. A remote attacker could use this flaw to
access running VM instances. (CVE-2015-7713)

Additional bug fixes include:

• Suspending an instance with a pre-created port that uses
  binding:vnic_type=‘direct’ previously failed; this has been fixed
  with an update to the API.(BZ#1196054)

• When using multipath-backed volumes using Object Storage (cinder),
  attach attempts failed without error. The handling of device
  identifiers has been updated and volumes can now be attached.
  (BZ#1206699)

• Previously, OpenStack Compute did not conform to PEP8 conventions;
  this has been fixed. (BZ#1278411)

• With a faulty lun in a multipath device, Compute tried to use the
  wrong device. Compute now uses the correct device, and instances
  can boot normally. (BZ#1280359)

• When using a FCoE adapter instead of a FC adapter, volumes
  previously failed to attach to the VM. This issue has been fixed.
  (BZ#1284033)

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