RHSA-2014:0422 - Security Advisory

Topic

Updated openshift-origin-broker and
rubygem-openshift-origin-auth-remote-user packages that fix one security
issue are now available for Red Hat OpenShift Enterprise 1.2.7.

The Red Hat Security Response Team has rated this update as having Critical
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.

Description

The openshift-origin-broker package provides the OpenShift Broker service
that manages all user logins, DNS name resolution, application states, and
general orchestration of the applications.

The rubygem-openshift-origin-auth-remote-user package provides the remote
user authentication plug-in.

A flaw was found in the way openshift-origin-broker handled authentication
requests via the remote user authentication plug-in. A remote attacker able
to submit a request to openshift-origin-broker could set the X-Remote-User
header, and send the request to a passthrough trigger, resulting in a
bypass of the authentication checks to gain access to any OpenShift user
account on the system. (CVE-2014-0188)

All users of Red Hat OpenShift Enterprise 1.2.7 are advised to upgrade to
these updated packages, which contain a backported patch to correct this
issue. After installing the updated packages, restart the httpd daemon for
this update to take effect.
