"The remote Oracle Linux 8 host has a package installed that is affected by multiple vulnerabilities as referenced in the
ELSA-2023-0821 advisory.

  - An invalid downcast from <code>nsTextNode</code> to <code>SVGElement</code> could have lead to undefined
    behavior.  (CVE-2023-25737)

  - When importing a SPKI RSA public key as ECDSA P-256, the key would be handled incorrectly causing the tab
    to crash.  (CVE-2023-25742)

  - Mozilla: Content security policy leak in violation reports using iframes (CVE-2023-25728)

  - Mozilla: Fullscreen notification not shown in Firefox Focus (CVE-2023-25743)

  - Mozilla developers Philipp and Gabriele Svelto reported memory safety bugs present in Thunderbird 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.  (CVE-2023-25746)

  - 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.  (CVE-2023-25729)

  - 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.  (CVE-2023-0767)

  - Module load requests that failed were not being checked as to whether or not they were cancelled causing a
    use-after-free in <code>ScriptLoadContext</code>.  (CVE-2023-25739)

  - Mozilla: User Interface lockup with messages combining S/MIME and OpenPGP (CVE-2023-0616)

  - 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.
    (CVE-2023-25730)

  - When encoding data from an <code>inputStream</code> in <code>xpcom</code> the size of the input being
    encoded was not correctly calculated potentially leading to an out of bounds memory write.
    (CVE-2023-25732)

  - Mozilla developers Kershaw Chang and the Mozilla Fuzzing Team reported memory safety bugs present in
    Firefox 109 and 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.  (CVE-2023-25744)

  - Cross-compartment wrappers wrapping a scripted proxy could have caused objects from other compartments to
    be stored in the main compartment resulting in a use-after-free after unwrapping the proxy.
    (CVE-2023-25735)

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