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.

All OpenShift Enterprise 3.0 and 3.1 users are advised to upgrade to
these updated packages, which correct this issue.
