[Buildroot] [PATCH 1/2] package/nghttp2: security bump to version 1.39.2

[Peter Korsgaard]

Fixes the following security issues:

CVE-2019-9511: Data Dribble
CVE-2019-9513: Resource Loop

For details, see the advisory:
https://nghttp2.org/blog/2019/08/19/nghttp2-v1-39-2/

Notice that libnghttp2 itself is not affected by these vulnerabilities, only
nghttpx and nghttpd (which are currently not built).

[Buildroot] [PATCH 2/2] package/nodejs: security bump to version v10.16.3

[Peter Korsgaard]

Fixes the following security vulnerabilities:

- 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.

Notice that this version bump requires nghttp2 1.39.2.  It also includes an
(unconditional) embedded copy of brotli.

Update the license hash because of copyright year changes and the addition
of the MIT-style license text for large_pages and brotli.

Committed to 2019.05.x and 2019.08.x, thanks.

For 2019.08.x I have instead bumped to v8.16.1, which fixes the same
list of issues.
