"The remote Ubuntu 14.04 LTS / 16.04 LTS / 18.04 LTS / 20.04 LTS / 22.04 LTS / 23.10 host has packages installed that are
affected by multiple vulnerabilities as referenced in the USN-6735-1 advisory.

  - 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)

  - The llhttp parser in the http module in Node v20.2.0 does not strictly use the CRLF sequence to delimit
    HTTP requests. This can lead to HTTP Request Smuggling (HRS). The CR character (without LF) is sufficient
    to delimit HTTP header fields in the llhttp parser. According to RFC7230 section 3, only the CRLF sequence
    should delimit each header-field. This impacts all Node.js active versions: v16, v18, and, v20
    (CVE-2023-30589)

  - The generateKeys() API function returned from crypto.createDiffieHellman() only generates missing (or
    outdated) keys, that is, it only generates a private key if none has been set yet, but the function is
    also needed to compute the corresponding public key after calling setPrivateKey(). However, the
    documentation says this API call: Generates private and public Diffie-Hellman key values. The documented
    behavior is very different from the actual behavior, and this difference could easily lead to security
    issues in applications that use these APIs as the DiffieHellman may be used as the basis for application-
    level security, implications are consequently broad. (CVE-2023-30590)

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