  - nodejs: Unitialized buffer due to incorrect encoding (CVE-2017-15897)

  - nodejs: integrity checks according to policies can be circumvented (CVE-2023-38552)

  - 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)

  - 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    outdated) keys, that is, it only generates a private key if none has been set yet, but the function is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)

  - Maliciously crafted export names in an imported WebAssembly module can inject JavaScript code. The
    injected code may be able to access data and functions that the WebAssembly module itself does not have
    access to, similar to as if the WebAssembly module was a JavaScript module. Impacts: Thanks to dittyroma
    for reporting the issue and to Tobias Nieen for fixing it. (CVE-2023-39333)

  - A vulnerability in the privateDecrypt() API of the crypto library, allowed a covert timing side-channel
    during PKCS#1 v1.5 padding error handling. The vulnerability revealed significant timing differences in
    decryption for valid and invalid ciphertexts. This poses a serious threat as attackers could remotely
    exploit the vulnerability to decrypt captured RSA ciphertexts or forge signatures, especially in scenarios
    involving API endpoints processing Json Web Encryption messages. Impacts: Thank you, to hkario for
    reporting this vulnerability and thank you Michael Dawson for fixing it. (CVE-2023-46809)

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