"The remote Rocky Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the
RLSA-2023:0808 advisory.

  - Mozilla developers Philipp and Gabriele Svelto reported memory safety bugs present in Firefox ESR 102.7.
    Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of
    these could have been exploited to run arbitrary code. This vulnerability affects Thunderbird < 102.8 and
    Firefox ESR < 102.8. (CVE-2023-25746)

  - An attacker could construct a PKCS 12 cert bundle in such a way that could allow for arbitrary memory
    writes via PKCS 12 Safe Bag attributes being mishandled. This vulnerability affects Firefox < 110,
    Thunderbird < 102.8, and Firefox ESR < 102.8. (CVE-2023-0767)

  - The <code>Content-Security-Policy-Report-Only</code> header could allow an attacker to leak a child
    iframe's unredacted URI when interaction with that iframe triggers a redirect. This vulnerability affects
    Firefox < 110, Thunderbird < 102.8, and Firefox ESR < 102.8. (CVE-2023-25728)

  - Permission prompts for opening external schemes were only shown for <code>ContentPrincipals</code>
    resulting in extensions being able to open them without user interaction via
    <code>ExpandedPrincipals</code>. This could lead to further malicious actions such as downloading files or
    interacting with software already installed on the system. This vulnerability affects Firefox < 110,
    Thunderbird < 102.8, and Firefox ESR < 102.8. (CVE-2023-25729)

  - A background script invoking <code>requestFullscreen</code> and then blocking the main thread could force
    the browser into fullscreen mode indefinitely, resulting in potential user confusion or spoofing attacks.
    This vulnerability affects Firefox < 110, Thunderbird < 102.8, and Firefox ESR < 102.8. (CVE-2023-25730)

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