"The remote Fedora 40 host has a package installed that is affected by multiple vulnerabilities as referenced in the
FEDORA-2024-eabe68b149 advisory.

  - A type check was missing when handling fonts in PDF.js, which would allow arbitrary JavaScript execution
    in the PDF.js context. This vulnerability affects Firefox < 126, Firefox ESR < 115.11, and Thunderbird <
    115.11. (CVE-2024-4367)

  - Multiple WebRTC threads could have claimed a newly connected audio input leading to use-after-free. This
    vulnerability affects Firefox < 126. (CVE-2024-4764)

  - Web application manifests were stored by using an insecure MD5 hash which allowed for a hash collision to
    overwrite another application's manifest. This could have been exploited to run arbitrary code in another
    application's context. *This issue only affects Firefox for Android. Other versions of Firefox are
    unaffected.* This vulnerability affects Firefox < 126. (CVE-2024-4765)

  - Different techniques existed to obscure the fullscreen notification in Firefox for Android. These could
    have lead to potential user confusion and spoofing attacks. *This bug only affects Firefox for Android.
    Other versions of Firefox are unaffected.* This vulnerability affects Firefox < 126. (CVE-2024-4766)

  - If the `browser.privatebrowsing.autostart` preference is enabled, IndexedDB files were not properly
    deleted when the window was closed. This preference is disabled by default in Firefox. This vulnerability
    affects Firefox < 126, Firefox ESR < 115.11, and Thunderbird < 115.11. (CVE-2024-4767)

  - A bug in popup notifications' interaction with WebAuthn made it easier for an attacker to trick a user
    into granting permissions. This vulnerability affects Firefox < 126, Firefox ESR < 115.11, and Thunderbird
    < 115.11. (CVE-2024-4768)

  - When importing resources using Web Workers, error messages would distinguish the difference between
    `application/javascript` responses and non-script responses. This could have been abused to learn
    information cross-origin. This vulnerability affects Firefox < 126, Firefox ESR < 115.11, and Thunderbird
    < 115.11. (CVE-2024-4769)

  - When saving a page to PDF, certain font styles could have led to a potential use-after-free crash. This
    vulnerability affects Firefox < 126, Firefox ESR < 115.11, and Thunderbird < 115.11. (CVE-2024-4770)

  - A memory allocation check was missing which would lead to a use-after-free if the allocation failed. This
    could have triggered a crash or potentially be leveraged to achieve code execution. This vulnerability
    affects Firefox < 126. (CVE-2024-4771)

  - An HTTP digest authentication nonce value was generated using `rand()` which could lead to predictable
    values. This vulnerability affects Firefox < 126. (CVE-2024-4772)

  - When a network error occurred during page load, the prior content could have remained in view with a blank
    URL bar. This could have been used to obfuscate a spoofed web site. This vulnerability affects Firefox <
    126. (CVE-2024-4773)

  - The `ShmemCharMapHashEntry()` code was susceptible to potentially undefined behavior by bypassing the move
    semantics for one of its data members. This vulnerability affects Firefox < 126. (CVE-2024-4774)

  - An iterator stop condition was missing when handling WASM code in the built-in profiler, potentially
    leading to invalid memory access and undefined behavior. *Note:* This issue only affects the application
    when the profiler is running. This vulnerability affects Firefox < 126. (CVE-2024-4775)

  - A file dialog shown while in full-screen mode could have resulted in the window remaining disabled. This
    vulnerability affects Firefox < 126. (CVE-2024-4776)

  - Memory safety bugs present in Firefox 125, Firefox ESR 115.10, and Thunderbird 115.10. 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 Firefox < 126, Firefox ESR < 115.11, and
    Thunderbird < 115.11. (CVE-2024-4777)

  - Memory safety bugs present in Firefox 125. 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 Firefox < 126. (CVE-2024-4778)

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