Security readout for executives and security teams
CVE-2017-2637 is a critical Red Hat OpenStack Platform director flaw where TripleO could deploy libvirtd for live migration on all interfaces without authentication or encryption. A reachable attacker could control virtual machine instances and may be able to take over compute hosts. Exposure is most likely in Red Hat OpenStack Platform director deployments using TripleO live migration where compute host libvirtd TCP is reachable from management networks or accidentally exposed beyond them. Treat as urgent for any affected OpenStack private cloud. Prioritize compute hosts because compromise could cross from infrastructure management into tenant VM control and possibly host takeover. Mitigation focus: Apply the relevant Red Hat RHSA updates for affected RHOSP director deployments.; Review Red Hat solution 3022771 and vendor guidance before changing production settings.; Restrict libvirtd TCP reachability to required trusted management paths only..
