"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.

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_release_notes.html

https://docs.openshift.com/container-platform/3.5/release_notes/
ocp_3_5_release_notes.html

https://docs.openshift.com/container-platform/3.4/release_notes/
ocp_3_4_release_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)."
