RHEL 7 : openstack-cinder, openstack-glance, and openstack-nova (RHSA-2017:0282)

high Nessus Plugin ID 210161

Synopsis

The remote Red Hat host is missing a security update for openstack-cinder / openstack-glance / openstack-nova.

Description

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2017:0282 advisory.

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)

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the RHEL openstack-cinder / openstack-glance / openstack-nova packages based on the guidance in RHSA-2017:0282.
