===================================================================== Red Hat Security Advisory
Synopsis: Moderate: openstack-nova security and bug fix update Advisory ID: RHSA-2018:0314-01 Product: Red Hat Enterprise Linux OpenStack Platform Advisory URL: https://access.redhat.com/errata/RHSA-2018:0314 Issue date: 2018-02-13 CVE Names: CVE-2017-16239 =====================================================================
1. Summary:
An update for openstack-nova is now available for Red Hat OpenStack Platform 11.0 (Ocata).
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 11.0 - 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.
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)
