The remote Fedora 38 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2023-ed41d3a922 advisory.

  - By displaying a prompt with a long description, the fullscreen notification could have been hidden,     resulting in potential user confusion or spoofing attacks. <br>*This bug only affects Firefox for Android.
    Other operating systems are unaffected.*. This vulnerability affects Firefox < 111. (CVE-2023-25748)

  - Android applications with unpatched vulnerabilities can be launched from a browser using Intents, exposing     users to these vulnerabilities. Firefox will now confirm with users that they want to launch an external     application before doing so. <br>*This bug only affects Firefox for Android. Other versions of Firefox are     unaffected.*. This vulnerability affects Firefox < 111. (CVE-2023-25749)

  - Under certain circumstances, a ServiceWorker's offline cache may have leaked to the file system when using     private browsing mode. This vulnerability affects Firefox < 111. (CVE-2023-25750)

  - Sometimes, when invalidating JIT code while following an iterator, the newly generated code could be     overwritten incorrectly. This could lead to a potentially exploitable crash. This vulnerability affects     Firefox < 111, Firefox ESR < 102.9, and Thunderbird < 102.9. (CVE-2023-25751)

  - When accessing throttled streams, the count of available bytes needed to be checked in the calling     function to be within bounds. This may have lead future code to be incorrect and vulnerable. This     vulnerability affects Firefox < 111, Firefox ESR < 102.9, and Thunderbird < 102.9. (CVE-2023-25752)

  - The fullscreen notification could have been hidden on Firefox for Android by using download popups,     resulting in potential user confusion or spoofing attacks. <br>*This bug only affects Firefox for Android.
    Other operating systems are unaffected.*. This vulnerability affects Firefox < 111. (CVE-2023-28159)

  - When following a redirect to a publicly accessible web extension file, the URL may have been translated to     the actual local path, leaking potentially sensitive information. This vulnerability affects Firefox <     111. (CVE-2023-28160)

  - If temporary one-time permissions, such as the ability to use the Camera, were granted to a document     loaded using a file: URL, that permission persisted in that tab for all other documents loaded from a     file: URL. This is potentially dangerous if the local files came from different sources, such as in a     download directory. This vulnerability affects Firefox < 111. (CVE-2023-28161)

  - While implementing AudioWorklets, some code may have casted one type to another, invalid, dynamic type.
    This could have led to a potentially exploitable crash. This vulnerability affects Firefox < 111, Firefox     ESR < 102.9, and Thunderbird < 102.9. (CVE-2023-28162)

  - When downloading files through the Save As dialog on Windows with suggested filenames containing     environment variable names, Windows would have resolved those in the context of the current user.
    <br>*This bug only affects Firefox on Windows. Other versions of Firefox are unaffected.*. This     vulnerability affects Firefox < 111, Firefox ESR < 102.9, and Thunderbird < 102.9. (CVE-2023-28163)

  - Dragging a URL from a cross-origin iframe that was removed during the drag could have led to user     confusion and website spoofing attacks. This vulnerability affects Firefox < 111, Firefox ESR < 102.9, and     Thunderbird < 102.9. (CVE-2023-28164)

  - Memory safety bugs present in Firefox 110 and Firefox ESR 102.8. 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 < 111, Firefox ESR < 102.9, and Thunderbird < 102.9.
    (CVE-2023-28176)

  - Memory safety bugs present in Firefox 110. 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 < 111. (CVE-2023-28177)

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