Synopsis: Moderate: openstack-nova security and bug fix advisory

Advisory ID: RHSA-2016:0013-01

Product: Red Hat Enterprise Linux OpenStack Platform

Advisory URL: https://rhn.redhat.com/errata/RHSA-2016-0013.html

Issue date: 2016-01-07

CVE Names: CVE-2015-7713

=====================================================================

 

1. Summary:

 

Updated openstack-nova packages that fix one security issue and

various bugs are now available for Red Hat Enterprise Linux OpenStack

Platform 6.0.

 

Red Hat Product Security has rated this update as having Moderate

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 6.0 for RHEL 7 - 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 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.

 

4. Solution:
