CVE-2021-3449  (opens in a new tab)
CWE-476  (opens in a new tab)

How to fix?

Upgrade node to version 15.14.0, 14.16.1, 12.22.1, 10.24.1 or higher.

Overview

node is a JavaScript runtime built on Chrome's V8 JavaScript engine.

Affected versions of this package are vulnerable to NULL Pointer Dereference. If sent a maliciously crafted renegotiation ClientHello message from a client, an OpenSSL TLS server may crash. If a TLSv1.2 renegotiation ClientHello omits the signature_algorithms extension (where it was present in the initial ClientHello), but includes a signature_algorithms_cert extension then a NULL pointer dereference will result, leading to a crash and a Denial of Service.
