"An update is now available for Red Hat OpenShift Container Platform
3.4, 3.5, 3.6, and 3.7.

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.

Security Fix(es) :

* A flaw was found in the way runc handled system file descriptors
when running containers. A malicious container could use this flaw to
overwrite contents of the runc binary and consequently run arbitrary
commands on the container host system. (CVE-2019-5736)

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

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."
