Topic

Updated openstack-nova packages that fix one security issue and
various bugs are now available for Red Hat Enterprise Linux OpenStack
Platform 6.0.

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.

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 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.
