Summary

OpenStack Orchestration (heat) 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 (heat), 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. (CVE-2015-5295)
This issue was discovered by Steven Hardy of Red Hat.
