How to fix?

Upgrade node to version 16.20.1, 18.16.1, 20.3.1 or higher.

Overview

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

Affected versions of this package are vulnerable to Buffer Over-read on 64-bit ARM systems using AES-XTS cipher decryption. Attackers in control of the size and location of the ciphertext buffer can cause a crash by supplying a buffer of length 4 mod 5 at a location just before unmapped memory.

NOTE: This issue can be patched by applying the fix commits to versions 3.0 and 3.1, but no dedicated fixed release is planned until the next scheduled one.
