Notable changes

Version 8.16.1 'Carbon' (LTS):
Notable changes
This is a security release.
Node.js, as well as many other implementations of HTTP/2, have been found
vulnerable to Denial of Service attacks.
See https://github.com/Netflix/security-bulletins/blob/master/advisories/third-party/2019-002.md
for more information.
Vulnerabilities fixed:
CVE-2019-9511 “Data Dribble”: The attacker requests a large amount of data from a specified resource over multiple streams. They manipulate window size and stream priority to force the server to queue the data in 1-byte chunks. Depending on how efficiently this data is queued, this can consume excess CPU, memory, or both, potentially leading to a denial of service.
CVE-2019-9512 “Ping Flood”: The attacker sends continual pings to an HTTP/2 peer, causing the peer to build an internal queue of responses. Depending on how efficiently this data is queued, this can consume excess CPU, memory, or both, potentially leading to a denial of service.
CVE-2019-9513 “Resource Loop”: The attacker creates multiple request streams and continually shuffles the priority of the streams in a way that causes substantial churn to the priority tree. This can consume excess CPU, potentially leading to a denial of service.
CVE-2019-9514 “Reset Flood”: The attacker opens a number of streams and sends an invalid request over each stream that should solicit a stream of RST_STREAM frames from the peer. Depending on how the peer queues the RST_STREAM frames, this can consume excess memory, CPU, or both, potentially leading to a denial of service.
CVE-2019-9515 “Settings Flood”: The attacker sends a stream of SETTINGS frames to the peer. Since the RFC requires that the peer reply with one acknowledgement per SETTINGS frame, an empty SETTINGS frame is almost equivalent in behavior to a ping. Depending on how efficiently this data is queued, this can consume excess CPU, memory, or both, potentially leading to a denial of service.
CVE-2019-9516 “0-Length Headers Leak”: The attacker sends a stream of headers with a 0-length header name and 0-length header value, optionally Huffman encoded into 1-byte or greater headers. Some implementations allocate memory for these headers and keep the allocation alive until the session dies. This can consume excess memory, potentially leading to a denial of service.
CVE-2019-9517 “Internal Data Buffering”: 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, potentially leading to a denial of service.
CVE-2019-9518 “Empty Frames Flood”: The attacker sends a stream of frames with an empty payload and without the end-of-stream flag. These frames can be DATA, HEADERS, CONTINUATION and/or PUSH_PROMISE. The peer spends time processing each frame disproportionate to attack bandwidth. This can consume excess CPU, potentially leading to a denial of service.

the http2 implementation to not crash under certain circumstances

- CVE-2018-7159
- CVE-2018-7160
Notable Changes
- Fix for inspector DNS rebinding vulnerability (CVE-2018-7160): A
malicious website could use a DNS rebinding attack to trick a web
browser to bypass same-origin-policy checks and allow HTTP connections
to localhost or to hosts on the local network, potentially to an open
inspector port as a debugger, therefore gaining full code execution
access. The inspector now only allows connections that have a browser
Host value of localhost or localhost6.
- Fix for 'path' module regular expression denial of service
(CVE-2018-7158): A regular expression used for parsing POSIX paths
could be used to cause a denial of service if an attacker were able to
have a specially crafted path string passed through one of the
impacted 'path' module functions.
- Reject spaces in HTTP Content-Length header values (CVE-2018-7159):
The Node.js HTTP parser allowed for spaces inside Content-Length
header values. Such values now lead to rejected connections in the
same way as non-numeric values.

added to the Node.js binary and 30 have been removed.
