"The remote Rocky Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the
RLSA-2024:1503 advisory.

  - On Linux, Node.js ignores certain environment variables if those may have been set by an unprivileged user
    while the process is running with elevated privileges with the only exception of CAP_NET_BIND_SERVICE. Due
    to a bug in the implementation of this exception, Node.js incorrectly applies this exception even when
    certain other capabilities have been set. This allows unprivileged users to inject code that inherits the
    process's elevated privileges. (CVE-2024-21892)

  - A vulnerability in Node.js HTTP servers allows an attacker to send a specially crafted HTTP request with
    chunked encoding, leading to resource exhaustion and denial of service (DoS). The server reads an
    unbounded number of bytes from a single connection, exploiting the lack of limitations on chunk extension
    bytes. The issue can cause CPU and network bandwidth exhaustion, bypassing standard safeguards like
    timeouts and body size limits. (CVE-2024-22019)

  - 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)
