Red Hat Security Advisory 2016-0441-01 - OpenStack Orchestration is a template-driven engine used to specify and deploy configurations for Compute, Storage, and OpenStack Networking. It can also be used to automate post-deployment actions, which in turn allows automated provisioning of infrastructure, services, and applications. Orchestration can also be integrated with Telemetry alarms to implement auto-scaling for certain infrastructure resources. A vulnerability was discovered in the OpenStack Orchestration service, where a specially formatted template could be used to trick the heat-engine service into opening a local file. Although the file contents are never disclosed to the end user, an OpenStack- authenticated attacker could use this flaw to cause a denial of service or determine whether a given file name is present on the server.
