"An update for atomic-openshift kube-apiserver is now available for Red
Hat OpenShift Container Platform 3.10.

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.

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) :

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

* containers/image: not enforcing TLS when sending username+password
credentials to token servers leading to credential disclosure
(CVE-2019-10214)

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."
