This is a security release. All Node.js users should consult the security
release summary at:
https://nodejs.org/en/blog/vulnerability/february-2019-security-releases/
for details on patched vulnerabilities.
Fixes for the following CVEs are included in this release:
* Node.js: Denial of Service with keep-alive HTTP connections
(CVE-2019-5739)
* Node.js: Slowloris HTTP Denial of Service with keep-alive
(CVE-2019-5737)
* OpenSSL: 0-byte record padding oracle (CVE-2019-1559)
Notable Changes:
* deps: OpenSSL has been upgraded to 1.0.2r which contains a fix for
CVE-2019-1559 (https://www.openssl.org/news/secadv/20190226.txt). Under
certain circumstances, a TLS server can be forced to respond differently to
a client if a zero-byte record is received with an invalid padding
compared to a zero-byte record with an invalid MAC. This can be used as the
basis of a padding oracle attack to decrypt data.
* http:
- Backport `server.keepAliveTimeout` to prevent keep-alive HTTP and HTTPS
connections remaining open and inactive for an extended period of time,
leading to a potential Denial of Service (DoS).
(CVE-2019-5739 / Timur Shemsedinov, Matteo Collina)
- Further prevention of "Slowloris" attacks on HTTP and HTTPS
connections by consistently applying the receive timeout set by
`server.headersTimeout` to connections in keep-alive mode. Reported by
Marco Pracucci (https://voxnest.com). (CVE-2019-5737 / Matteo Collina)

In openssl s_client on Windows, RAND_screen() is invoked to initialize
random state but it takes several seconds in each connection.
This added -no_rand_screen to openssl s_client on Windows to skip
RAND_screen() and gets a better performance in the unit test of
test-tls-server-verify.
Do not enable this except to use in the unit test.

All symlink files in `deps/openssl/openssl/include/openssl/`
are removed and replaced with real header files to avoid
issues on Windows. Two files of opensslconf.h in crypto and
include dir are replaced to refer config/opensslconf.h.
The test is flaky under load. These changes greatly improve reliability.
* Use a recurring interval to determine when the test should end rather
than a timer.
* Increase server timeout to 500ms to allow for events being delayed by
system load
Changing to an interval has the added benefit of reducing the test run
time from over 2 seconds to under 1 second.

Fix the logic of resetting the socket timeout of keep-alive HTTP
connections and add two tests:
* `test-http-server-keep-alive-timeout-slow-server` is a regression test
for GH-13391. It ensures that the server-side keep-alive timeout will
not fire during processing of a request.
* `test-http-server-keep-alive-timeout-slow-client-headers` ensures that
the regular socket timeout is restored as soon as a client starts
sending a new request, not as soon as the whole message is received,
so that the keep-alive timeout will not fire while, e.g., the client
is sending large cookies.

The 6.15.0 security release introduced some unexpected breakages on
the 6.x release line. This is a special release to fix a regression
in the HTTP binary upgrade response body and add a missing CLI flag
to adjust the max header size of the http parser.
Notable changes:
* cli:
- add --max-http-header-size flag (cjihrig)
https://github.com/nodejs/node/pull/24811
* http:
- add maxHeaderSize property (cjihrig)

This is a security release. All Node.js users should consult the security
release summary at:
https://nodejs.org/en/blog/vulnerability/november-2018-security-releases/
for details on patched vulnerabilities.
Fixes for the following CVEs are included in this release:
* Node.js: Debugger port 5858 listens on any interface by default
(CVE-2018-12120)
* Node.js: Denial of Service with large HTTP headers (CVE-2018-12121)
* Node.js: Slowloris HTTP Denial of Service (CVE-2018-12122 / Node.js)
* Node.js: Hostname spoofing in URL parser for javascript protocol
(CVE-2018-12123)
* Node.js: HTTP request splitting (CVE-2018-12116)
* OpenSSL: Timing vulnerability in DSA signature generation (CVE-2018-0734)
* OpenSSL: Microarchitecture timing vulnerability in ECC scalar multiplication
(CVE-2018-5407)
Notable Changes:
* debugger: Backport of https://github.com/nodejs/node/pull/8106 to
prevent the debugger from listening on `0.0.0.0`. It now defaults to
`127.0.0.1`. Reported by Ben Noordhuis. (CVE-2018-12120 / Ben Noordhuis).
* deps: Upgrade to OpenSSL 1.0.2q, fixing CVE-2018-0734 and CVE-2018-5407
* http:
* Headers received by HTTP servers must not exceed 8192 bytes in total to
prevent possible Denial of Service attacks. Reported by Trevor Norris.
(CVE-2018-12121 / Matteo Collina)
* A timeout of 40 seconds now applies to servers receiving HTTP headers. This
value can be adjusted with `server.headersTimeout`. Where headers are not
completely received within this period, the socket is destroyed on the next
received chunk. In conjunction with `server.setTimeout()`, this aids in
protecting against excessive resource retention and possible Denial of
Service. Reported by Jan Maybach (liebdich.com).
(CVE-2018-12122 / Matteo Collina)
* Two-byte characters are now strictly disallowed for the `path` option in
HTTP client requests. Paths containing characters outside of the range
`\u0021` - `\u00ff` will now be rejected with a `TypeError`. This behavior
can be reverted if necessary by supplying the
`--security-revert=CVE-2018-12116` command line argument (this is not
recommended). Reported as security concern for Node.js 6 and 8 by
Arkadiy Tetelman (lob.com), fixed by backporting a change by Benno
Fünfstück applied to Node.js 10 and later.
(CVE-2018-12116 / Matteo Collina)
* url: Fix a bug that would allow a hostname being spoofed when parsing
URLs with `url.parse()` with the `'javascript:'` protocol. Reported by
Martin Bajanik (kenticocloud.com). (CVE-2018-12123 / Matteo Collina)
