"Updated openshift packages that fix one security issue are now
available for Red Hat OpenShift Enterprise 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.

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.

An access flaw was discovered in OpenShift; the
/etc/origin/master/master-config.yaml configuration file, which could
contain Active Directory credentials, was world-readable. A local user
could exploit this flaw to obtain authentication credentials from the
master-config.yaml file. (CVE-2016-2142)

If you believe that the password in this file has been viewed by an
attacker you should reset the password after installing this update.

All installations with Active Directory integration are advised to
upgrade to the updated software, which contains a backported patch to
correct this issue.
