1. Summary:
An updated openstack-heat-templates package that fixes three security
issues is now available Red Hat Enterprise Linux OpenStack Platform 4.0.
The Red Hat Security Response Team has rated this update as having Low
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.
2. Relevant releases/architectures:
Red Hat Enterprise Linux OpenStack Platform 4.0 - noarch
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.
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.
