openSUSE Leap 15.2: 2021:0064-1 Moderate: Nodejs12 Memory Exploit Fix

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

allocated WriteWrap object as first argument. If the DoWrite method

does not return an error, this object is passed back to the caller as

(https://cwe.mitre.org/data/definitions/444.html). (bsc#1180554)
