nodejs4/CVE-2018-12120.patch
Adam Majer 3f386ef218 Backport security fixes from NodeJS 6.x: 
* debugger: prevent the debugger from listening on 0.0.0.0.
    It now defaults to 127.0.0.1.
    CVE-2018-12120.patch - (CVE-2018-12120, bsc#1117625)
  * http:
    + 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).
      CVE-2018-12116.patch - (CVE-2018-12116, bsc#1117630)
  * util: Fix a bug that would allow a hostname being spoofed when
    parsing URLs with url.parse() with the 'javascript:' protocol.
    CVE-2018-12123.patch - (CVE-2018-12123, bnc#1117629)

Subject: [PATCH] src: make debugger listen on 127.0.0.1 by default
CVE-2018-12120
Backport of 8e7cbe2 to v6.x
Prepared by Sam Roberts <vieuxtech@gmail.com>
Original commit:
Commit 2272052 ("net: bind to `::` TCP address by default") from
April 2014 seems to have accidentally changed the default listen
address from 127.0.0.1 to 0.0.0.0, a.k.a. the "any" address.
From a security viewpoint it's undesirable to accept debug agent
connections from anywhere so let's change that back. Users can
override the default with the `--debug=<host>:<port>` switch.
