This update for nodejs12 fixes the following issues:

- New upstream LTS version 12.20.1:
* CVE-2020-8265: use-after-free in TLSWrap (High) bug in TLS
implementation. When writing to a TLS enabled socket,
node::StreamBase::Write calls node::TLSWrap::DoWrite with
a freshly allocated WriteWrap object as first argument.
If the DoWrite method does not return an error, this object is
passed back to the caller as part of a StreamWriteResult structure.
This may be exploited to corrupt memory leading to a
Denial of Service or potentially other exploits (bsc#1180553)
* CVE-2020-8287: HTTP Request Smuggling allow two copies of a
header field in a http request. For example, two Transfer-Encoding
header fields. In this case Node.js identifies the first header
field and ignores the second. This can lead to HTTP Request
Smuggling (https://cwe.mitre.org/data/definitions/444.html).
(bsc#1180554)
* CVE-2020-1971: OpenSSL - EDIPARTYNAME NULL pointer de-reference
(High) This is a vulnerability in OpenSSL which may be exploited
through Node.js. (bsc#1179491)

- New upstream LTS version 12.20.0:
* deps:
+ update llhttp '2.1.2' -> '2.1.3'
+ update uv '1.39.0' -> '1.40.0'
+ update uvwasi '0.0.10' -> '0.0.11'
* fs: add .ref() and .unref() methods to watcher classes
* http: added scheduling option to http agent
* module:
+ exports pattern support
+ named exports for CJS via static analysis
* n-api: add more property defaults (gh#35214)

- New upstream LTS version 12.19.1:
* deps: Denial of Service through DNS request (High).
A Node.js application that allows an attacker to trigger a DNS
request for a host of their choice could trigger a Denial of Service
by getting the application to resolve a DNS record with
a larger number of responses (bsc#1178882, CVE-2020-8277)

- New upstream LTS version 12.19.0:
* crypto: add randomInt function
* deps:
+ upgrade to libuv 1.39.0
+ deps: upgrade npm to 6.14.7
+ deps: upgrade to libuv 1.38.1
* doc: deprecate process.umask() with no arguments
* module:
+ package "imports" field
+ module: deprecate module.parent
* n-api: create N-API version 7
* zlib: switch to lazy init for zlib streams
