Description

A vulnerability was found in NodeJS due to weak randomness in the WebCrypto keygen within the SecretKeyGenTraits::DoKeyGen() in src/crypto/crypto_keygen.cc. Node.js made calls to EntropySource() in SecretKeyGenTraits::DoKeyGen(). However, it does not check the return value and assumes the EntropySource() always succeeds, but it can and sometimes will fail. This flaw allows a remote attacker to decrypt sensitive information.

Statement

The vulnerability was introduced in NodeJS v15.0.0, Hence, NodeJS:14 package in RHEL-8 and RHSCL-3 are not affected.
