"From Red Hat Security Advisory 2019:2925 :

An update for the nodejs:10 module is now available for Red Hat
Enterprise Linux 8.

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.

Node.js is a software development platform for building fast and
scalable network applications in the JavaScript programming language.

The following packages have been upgraded to a later upstream version:
nodejs (10.16.3).

Security Fix(es) :

* HTTP/2: large amount of data requests leads to denial of service
(CVE-2019-9511)

* HTTP/2: flood using PING frames results in unbounded memory growth
(CVE-2019-9512)

* HTTP/2: flood using PRIORITY frames results in excessive resource
consumption (CVE-2019-9513)

* HTTP/2: flood using HEADERS frames results in unbounded memory
growth (CVE-2019-9514)

* HTTP/2: flood using SETTINGS frames results in unbounded memory
growth (CVE-2019-9515)

* HTTP/2: 0-length headers lead to denial of service (CVE-2019-9516)

* HTTP/2: request for large response leads to denial of service
(CVE-2019-9517)

* HTTP/2: flood using empty frames results in excessive resource
consumption (CVE-2019-9518)

For more details about the security issue(s), including the impact, a
CVSS score, acknowledgments, and other related information, refer to
