Topic

Updated OpenStack Orchestration packages that fix one security issue and
two bugs are now available for Red Hat Enterprise Linux OpenStack
Platform 5.0 (Icehouse) for RHEL 7.

Red Hat Product Security has rated this update as having Moderate security
impact. Common Vulnerability Scoring System (CVSS) base scores, which give
detailed severity ratings, are available for each vulnerability from the
CVE links in the References section.

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.
