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) 4.
