"An update for atomic-openshift is now available for Red Hat OpenShift
Container Platform 3.9.

Red Hat Product Security has rated this update as having a security
impact of Important. 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.

Red Hat OpenShift Container Platform is Red Hat's cloud computing
Kubernetes application platform solution designed for on-premise or
private cloud deployments.

This advisory contains the atomic-openshift RPM package for Red Hat
OpenShift Container Platform 3.9.102.

Security Fix(es) :

* kubernetes: YAML parsing vulnerable to 'Billion Laughs' attack,
allowing for remote denial of service (CVE-2019-11253)

* atomic-openshift: OpenShift builds don't verify SSH Host Keys for
the Git repository (CVE-2019-10150)

* kubernetes: Incomplete fixes for CVE-2019-1002101 and
CVE-2019-11246, kubectl cp potential directory traversal
(CVE-2019-11249)

* kubernetes: `kubectl cp` allows for arbitrary file write via double
symlinks (CVE-2019-11251)

For more details about the security issue(s), including the impact, a
CVSS score, acknowledgments, and other related information, refer to
the CVE page(s) listed in the References section."
