Summary
Red Hat Security Advisory: Red Hat OpenStack Platform director security update

Notes

Topic
An update is now available for Red Hat OpenStack Platform 7.0 (Kilo). Red Hat Product Security has rated this update as having a security impact of Important. 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.
Details
Red Hat OpenStack Platform director provides the facilities for deploying and monitoring a private or public infrastructure-as-a-service (IaaS) cloud based on Red Hat OpenStack Platform. Security Fix(es): * A design flaw issue was found in the Red Hat OpenStack Platform director use of TripleO to enable libvirtd based live-migration. Libvirtd is deployed by default (by director) listening on 0.0.0.0 (all interfaces) with no-authentication or encryption. Anyone able to make a TCP connection to any compute host IP address, including 127.0.0.1, other loopback interface addresses, or in some cases possibly addresses that have been exposed beyond the management interface, could use this to open a virsh session to the libvirtd instance and gain control of virtual machine instances or possibly take over the host. (CVE-2017-2637) A KCS article with more information on this flaw is available at: https://access.redhat.com/solutions/3022771 This issue was discovered by David Gurtner (Red Hat).
