RHEL 7 : openstack-nova (RHSA-2018:0314)

medium Nessus Plugin ID 194019

Language:

Synopsis

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

Description

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2018:0314 advisory.

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.

Security Fix(es):

* By rebuilding an instance using a new image, an authenticated user may be able to circumvent the Filter Scheduler, bypassing imposed filters (for example, the ImagePropertiesFilter or the IsolatedHostsFilter).
(CVE-2017-16239)

Red Hat would like to thank the OpenStack project for reporting this issue. Upstream acknowledges George Shuklin (Servers.com) as the original reporter.

Bug Fix(es):

* A recent update caused OpenStack Compute to ignore the disk cache mode configuration. This caused I/O performance degradation in instances. This fix corrects how OpenStack Compute configures disk caching.
Instances no longer suffer performance degradation. (BZ#1508647)

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-nova package based on the guidance in RHSA-2018:0314.
