=====================================================================

1. Summary:

An update is now available for Red Hat OpenShift Container Platform 3.4,
Red Hat OpenShift Container Platform 3.5, and Red Hat OpenShift Container
Platform 3.6.

Red Hat Product Security has rated this update as having a security impact
of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which
gives a detailed severity rating, is available for each vulnerability from
the CVE link(s) in the References section.

2. Relevant releases/architectures:

Red Hat OpenShift Container Platform 3.4 - noarch, x86_64
Red Hat OpenShift Container Platform 3.5 - noarch, x86_64
Red Hat OpenShift Container Platform 3.6 - noarch, x86_64

3. 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.

This advisory contains the RPM packages for this release. An advisory for
the container images for this release is available at:
https://access.redhat.com/errata/RHBA-2017:3390.

Space precludes documenting all of the bug fixes and enhancements in this
advisory. See the following Release Notes documentation, which will be
updated shortly for this release, for details about these changes:

https://docs.openshift.com/container-platform/3.6/release_notes/ocp_3_6_rel
ease_notes.html

https://docs.openshift.com/container-platform/3.5/release_notes/ocp_3_5_rel
ease_notes.html

https://docs.openshift.com/container-platform/3.4/release_notes/ocp_3_4_rel
ease_notes.html

All OpenShift Container Platform 3 users are advised to upgrade to these
updated packages and images.

Security Fix(es):

* An attacker with knowledge of the given name used to authenticate and
access Elasticsearch can later access it without the token, bypassing
authentication. This attack also requires that the Elasticsearch be
configured with an external route, and the data accessed is limited to the
indices. (CVE-2017-12195)

This issue was discovered by Rich Megginson (Red Hat).

4. Solution:
