Affected: AlmaLinux:8: nodejs-nodemon, AlmaLinux:8: nodejs-packaging

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)

Affected: CleanStart: nodejs

Multiple security vulnerabilities affect the nodejs package. These issues are resolved in later releases. See references for individual vulnerability details.

Some HTTP/2 implementations are vulnerable to unconstrained interal data buffering, potentially leading to a denial of service. The attacker opens the HTTP/2 window so the peer can send without constraint; however, they leave the TCP window closed so the peer cannot actually write (many of) the bytes on the wire. The attacker then sends a stream of requests for a large response object. Depending on how the servers queue the responses, this can consume excess memory, CPU, or both.
