Red Hat Security Advisory: nodejs:10 security update
Notes
Topic
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.
Details
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)
