Red Hat Security Advisory

 

Synopsis: Moderate: openstack-cinder, openstack-glance, and openstack-nova security update

Advisory ID: RHSA-2017:0282-01

Product: Red Hat Enterprise Linux OpenStack Platform

Advisory URL: https://rhn.redhat.com/errata/RHSA-2017-0282.html

Issue date: 2017-02-15

CVE Names: CVE-2015-5162

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

 

1. Summary:

 

An update for openstack-nova, openstack-cinder, openstack-glance, and

python-oslo-concurrency is now available for Red Hat Enterprise Linux

OpenStack Platform 7.0 (Kilo) for RHEL 7.

 

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 Enterprise Linux OpenStack Platform 7.0 (Kilo) for RHEL 7 - noarch

 

3. Description:

 

The Oslo concurrency library has utilities for safely running multi-thread,

multi-process applications using locking mechanisms, and for running

external processes.

 

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 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.

 

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.

Programmatic management is available via Block Storage's API.

 

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.

oslo.concurrency has been updated to support process limits ('prlimit'),

which is needed to fix this flaw. (CVE-2015-5162)

 

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

 

Bug Fix(es):

 

* qemu-img calls were unrestricted by ulimit. oslo.concurrency has been

updated to add support for process limits ('prlimit'), which is needed to

fix the CVE-2015-5162 security vulnerability. (BZ#1383415)
