"The remote Rocky Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the
RLSA-2022:6964 advisory.

  - The llhttp parser in the http module in Node v18.7.0 does not correctly handle header fields that are not
    terminated with CLRF. This may result in HTTP Request Smuggling. (CVE-2022-35256)

  - 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. (CVE-2022-35255)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
