"An update for jss is now available for Red Hat Enterprise Linux 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.

Java Security Services (JSS) provides an interface between Java
Virtual Machine and Network Security Services (NSS). It supports most
of the security standards and encryption technologies supported by NSS
including communication through SSL/TLS network protocols. JSS is
primarily utilized by the Certificate Server as a part of the Identity
Management System.

Security Fix(es) :

* JSS: OCSP policy 'Leaf and Chain' implicitly trusts the root
certificate (CVE-2019-14823)

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."
