NVD Description

Note: Versions mentioned in the description apply only to the upstream nodejs16 package and not the nodejs16 package as distributed by SLES. See How to fix? for SLES:15.3 relevant fixed versions and status.

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.
