+## 2021-01-04, Version 12.20.1 'Erbium' (LTS), @richardlau
+
+### 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,
+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
+* **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.
+You can read more about it in
+https://www.openssl.org/news/secadv/20201208.txt
