CVE-2022-35255: Debian Linux

Critical severity, CVSS 9.1. EPSS: 2.1% chance of exploitation in the next 30 days.

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.

• Node.js Node.js: from 15.0.0, up to and including 15.14.0; from 16.0.0, up to and including 16.12.0; from 16.13.0, before 16.17.1 (fixed in 16.17.1); from 18.0.0, before 18.9.1 (fixed in 18.9.1)
