"The version of firefox installed on the remote host is prior to 102.9.0-1. It is, therefore, affected by multiple
vulnerabilities as referenced in the ALAS2FIREFOX-2023-004 advisory.

  - 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)

  - 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)

  - Mozilla developers Timothy Nikkel, Andrew McCreight, and the Mozilla Fuzzing Team reported 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)

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