Release notes

Notable changes
This is a security release.
Vulnerabilities fixed:
- CVE-2020-8265: use-after-free in TLSWrap (High)
Affected Node.js versions are vulnerable to a use-after-free bug in its
TLS implementation. When writing to a TLS enabled socket,
nodeStreamBaseWrite calls nodeTLSWrapDoWrite 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
- CVE-2020-8287: HTTP Request Smuggling in nodejs
Affected versions of Node.js 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).
- CVE-2020-1971: OpenSSL - EDIPARTYNAME NULL pointer de-reference (High)
This is a vulnerability in OpenSSL which may be exploited through Node.js.
