CVE-2022-35255 Weak cryptography in Node

What is CVE-2022-35255?

CVE-2022-35255 is a critical vulnerability in Debian Debian Linux, published on 5 Dec 2022. An attacker can exploit it over the internet without logging in, with no action from the victim.

Official description

A weak randomness in WebCrypto keygen vulnerability exists in Node.js 18 due to a change with EntropySource() in SecretKeyGenTraits::DoKeyGen() in src/crypto/crypto_keygen.cc. There are two problems with this: 1) It does not check the return value, it assumes EntropySource() always succeeds, but it can (and sometimes will) fail. 2) The random data returned byEntropySource() may not be cryptographically strong and therefore not suitable as keying material.

Weakness: CWE-338
