Red Hat Security Advisory

Synopsis: Moderate: openstack-cinder, openstack-glance, and
openstack-nova update
Advisory ID: RHSA-2016:2991-01
Product: Red Hat Enterprise Linux OpenStack Platform
Advisory URL:
Issue date: 2016-12-21
CVE Names: CVE-2015-5162

1. Summary:

An update for openstack-nova, openstack-cinder, and openstack-glance is now
available for Red Hat OpenStack Platform 8.0 (Liberty).

Red Hat Product Security has rated this update as having a security impact
of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which
gives a detailed severity rating, is available for each vulnerability from
the CVE link(s) in the References section.

2. Relevant releases/architectures:

Red Hat OpenStack Platform 8.0 (Liberty) - 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.

OpenStack Block Storage (cinder) manages block storage mounting and the
presentation of such mounted block storage to instances. The backend
physical storage can consist of local disks, or Fiber Channel, iSCSI, and
NFS mounts attached to Compute nodes. In addition, Block Storage supports
volume backups, and snapshots for temporary save and restore operations.
Programatic management is available via Block Storage's API.

OpenStack Image Service (glance) provides discovery, registration, and
delivery services for disk and server images. The service provides the
ability to copy or snapshot a server image, and immediately store it away.
Stored images can be used as a template to get new servers up and running
quickly and more consistently than installing a server operating system and
individually configuring additional services.

The following packages have been upgraded to a newer upstream version:
openstack-nova (12.0.5), openstack-cinder (7.0.3), openstack-glance
(11.0.1). (BZ#1381466, BZ#1396263)

Security Fix(es):

* A resource vulnerability in the OpenStack Compute (nova), Block Storage
(cinder), and Image (glance) services was found in their use of qemu-img.
An unprivileged user could consume as much as 4 GB of RAM on the compute
host by uploading a malicious image. This flaw could lead possibly to host
out-of-memory errors and negatively affect other running tenant instances.

This issue was discovered by Richard W.M. Jones (Red Hat).

Bug Fix(es):

* There is a known issue with Unicode string handling in the OSProfiler
library. Consequently, the creation of a Block Storage (cinder) snapshot
will fail if it uses non-ASCII characters. With this update, the OSProfiler
library is not loaded unless it is specifically enabled in the cinder
configuration. As a result, the Unicode handling issue in OSProfiler is
still present, and will result in the same failure if OSProfiler is used,
however it will be unlikely to occur in most cinder configurations. A more
in-depth resolution for this issue is not currently in scope. (BZ#1383899)
