[Buildroot] [git commit branch/2020.11.x] package/nodejs: security bump to version v12.21.0

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=ccce1301b297ed3670ef1ff6580d05f34d6d280d
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2020.11.x

Fixes the following security issues:

CVE-2021-22883: HTTP2 'unknownProtocol' cause Denial of Service by resource exhaustion

Affected Node.js versions are vulnerable to denial of service attacks when
too many connection attempts with an 'unknownProtocol' are established.
This leads to a leak of file descriptors.  If a file descriptor limit is
configured on the system, then the server is unable to accept new
connections and prevent the process also from opening, e.g.  a file.  If no
file descriptor limit is configured, then this lead to an excessive memory
usage and cause the system to run out of memory.

CVE-2021-22884: DNS rebinding in --inspect

Affected Node.js versions are vulnerable to denial of service attacks when
the whitelist includes ???localhost6???.  When ???localhost6??? is not present in
/etc/hosts, it is just an ordinary domain that is resolved via DNS, i.e.,
over network.  If the attacker controls the victim's DNS server or can spoof
its responses, the DNS rebinding protection can be bypassed by using the
???localhost6??? domain.  As long as the attacker uses the ???localhost6??? domain,
they can still apply the attack described in CVE-2018-7160.
