(RHSA-2018:2855) Moderate: openstack-nova security and bug fix update

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):

• openstack-nova: Swapping encrypted volumes can allow an attacker to corrupt the LUKS header causing a denial of service in the host (CVE-2017-18191)

For more details about the security issue(s), including the impact, a CVSS score, and other related information, refer to the CVE page(s) listed in the References section.

Bug Fix(es):

• This update fixes a race condition that could generate error messages and cause migration failures during nova live migrations.

Prior to this update, if a domain was already cleaned out by periodic tasks, undefining the domain source during a live migration sometimes generated a “Domain not found (Code=42)” error. (BZ#1614325)
