"The remote Rocky Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the
RLSA-2023:7205 advisory.

  - When the Node.js policy feature checks the integrity of a resource against a trusted manifest, the
    application can intercept the operation and return a forged checksum to the node's policy implementation,
    thus effectively disabling the integrity check. Impacts: This vulnerability affects all users using the
    experimental policy mechanism in all active release lines: 18.x and, 20.x. Please note that at the time
    this CVE was issued, the policy mechanism is an experimental feature of Node.js. (CVE-2023-38552)

  - A previously disclosed vulnerability (CVE-2023-30584) was patched insufficiently in commit 205f1e6. The
    new path traversal vulnerability arises because the implementation does not protect itself against the
    application overwriting built-in utility functions with user-defined implementations. Please note that at
    the time this CVE was issued, the permission model is an experimental feature of Node.js. (CVE-2023-39331)

  - Various `node:fs` functions allow specifying paths as either strings or `Uint8Array` objects. In Node.js
    environments, the `Buffer` class extends the `Uint8Array` class. Node.js prevents path traversal through
    strings (see CVE-2023-30584) and `Buffer` objects (see CVE-2023-32004), but not through non-`Buffer`
    `Uint8Array` objects. This is distinct from CVE-2023-32004 which only referred to `Buffer` objects.
    However, the vulnerability follows the same pattern using `Uint8Array` instead of `Buffer`. Please note
    that at the time this CVE was issued, the permission model is an experimental feature of Node.js.
    (CVE-2023-39332)

  - The HTTP/2 protocol allows a denial of service (server resource consumption) because request cancellation
    can reset many streams quickly, as exploited in the wild in August through October 2023. (CVE-2023-44487)

  - Undici is an HTTP/1.1 client written from scratch for Node.js. Prior to version 5.26.2, Undici already
    cleared Authorization headers on cross-origin redirects, but did not clear `Cookie` headers. By design,
    `cookie` headers are forbidden request headers, disallowing them to be set in RequestInit.headers in
    browser environments. Since undici handles headers more liberally than the spec, there was a disconnect
    from the assumptions the spec made, and undici's implementation of fetch. As such this may lead to
    accidental leakage of cookie to a third-party site or a malicious attacker who can control the redirection
    target (ie. an open redirector) to leak the cookie to the third party site. This was patched in version
    5.26.2. There are no known workarounds. (CVE-2023-45143)

  - 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)

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