"The remote Redhat Enterprise Linux 8 host has one or more packages installed that are affected by multiple
vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - nodejs: DiffieHellman do not generate keys after setting a private key (CVE-2023-30590)

  - The use of __proto__ in process.mainModule.__proto__.require() can bypass the policy mechanism and require
    modules outside of the policy.json definition. This vulnerability affects all users using the experimental
    policy mechanism in all active release lines: v16, v18 and, v20. Please note that at the time this CVE was
    issued, the policy is an experimental feature of Node.js (CVE-2023-30581)

  - When an invalid public key is used to create an x509 certificate using the crypto.X509Certificate() API a
    non-expect termination occurs making it susceptible to DoS attacks when the attacker could force
    interruptions of application processing, as the process terminates when accessing public key info of
    provided certificates from user code. The current context of the users will be gone, and that will cause a
    DoS scenario. This vulnerability affects all active Node.js versions v16, v18, and, v20. (CVE-2023-30588)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package
is installed.");
