2019-08-15, Version 8.16.1 'Carbon' (LTS)

This is a security release.

Notable changes:

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. (Discovered by Piotr Sikora of Google)
