=====================================================================
1. Summary:
Updated openshift images that fix one security issue are now
available for Red Hat OpenShift Enterprise 3.0 and 3.1.
Red Hat Product Security has rated this update as having Moderate
security impact. A Common Vulnerability Scoring System (CVSS) base
score, which gives a detailed severity rating, is available from the
CVE link in the References section.
2. Description:
OpenShift Enterprise by Red Hat is the company's cloud computing
Platform-as-a-Service (PaaS) solution designed for on-premise or
private cloud deployments.
It was found that OpenShift's API back end did not verify requests for
pod log locations, allowing a pod on a Node to request logs for any
other pod on that Node. A remote attacker could use this flaw to view
sensitive information via pod logs that they would normally not have
access to. (CVE-2015-7528)
This issue was discovered by Jordan Liggitt of Red Hat Atomic OpenShift.
To use the latest 'openshift3/ose:v3.1.0.4' image with the ID
"d4caa301790e" simply run the following command:
docker pull registry.access.redhat.com/openshift3/ose:v3.1.0.4
and then restart any containers based on this image.
All OpenShift Enterprise 3.0 and 3.1 users are advised to upgrade to
these updated images, which correct this issue.

Before applying this update, make sure all previously released errata
relevant to your system have been applied.
