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

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.
