Topic

An updated openstack-heat-templates package that fixes three security
issues is now available Red Hat Enterprise Linux OpenStack Platform 4.0.

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.

The openstack-heat-templates package provides heat example templates and
image building elements for the openstack-heat package.

It was discovered that certain heat templates used HTTP to insecurely
download packages and signing keys via Yum. An attacker could use this flaw
to conduct man-in-the-middle attacks to prevent essential security updates
from being installed on the system. (CVE-2014-0040)

It was found that certain heat templates disabled SSL protection for
various Yum repositories (sslverify=false). An attacker could use this flaw
to conduct man-in-the-middle attacks to prevent essential security updates
from being installed on the system. (CVE-2014-0041)

It was discovered that certain heat templates disabled GPG signature
checking of packages via Yum (gpgcheck=0). An attacker could use this flaw
to conduct man-in-the-middle attacks to install arbitrary packages on the
system. (CVE-2014-0042)

These issues were discovered by Grant Murphy of the Red Hat Product
Security Team.

All openstack-heat-templates users are advised to upgrade to this updated
package, which corrects these issues.
