2. Relevant releases/architectures:

3. Description:

 

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.
