Notable Changes
This is planned to be the final Node.js 12 release. Node.js 12 will
reach End-of-Life status on 30 April 2022, after which it will no
receive updates. You are strongly advised to migrate your applications
to Node.js 16 or 14 (both of which are Long Term Support (LTS) releases)
to continue to receive future security updates beyond 30 April 2022.
This release fixes a shutdown crash in Node-API (formerly N-API) and a
potential stack overflow when using vm.runInNewContext().
The list of GPG keys used to sign releases and instructions on how to
fetch the keys for verifying binaries has been synchronized with the
main branch.

12.22.9 Jan 10, 2022

This is a security release.
Notable changes
Improper handling of URI Subject Alternative Names (Medium)(CVE-2021-44531)
Accepting arbitrary Subject Alternative Name (SAN) types, unless a PKI is specifically defined to use a particular SAN type, can result in bypassing name-constrained intermediates. Node.js was accepting URI SAN types, which PKIs are often not defined to use. Additionally, when a protocol allows URI SANs, Node.js did not match the URI correctly.
Versions of Node.js with the fix for this disable the URI SAN type when checking a certificate against a hostname. This behavior can be reverted through the --security-revert command-line option.
More details will be available at CVE-2021-44531 after publication.
Certificate Verification Bypass via String Injection (Medium)(CVE-2021-44532)
Node.js converts SANs (Subject Alternative Names) to a string format. It uses this string to check peer certificates against hostnames when validating connections. The string format was subject to an injection vulnerability when name constraints were used within a certificate chain, allowing the bypass of these name constraints.
Versions of Node.js with the fix for this escape SANs containing the problematic characters in order to prevent the injection. This behavior can be reverted through the --security-revert command-line option.
More details will be available at CVE-2021-44532 after publication. …
