"The version of mozilla-firefox installed on the remote host is prior to 101.0 / 91.10.0esr. It is, therefore, affected
by multiple vulnerabilities as referenced in the SSA:2022-151-01 advisory.

  - Mozilla developers Andrew McCreight, Nicolas B. Pierron, and the Mozilla Fuzzing Team reported memory
    safety bugs present in Firefox 100 and Firefox ESR 91.9. 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 < 91.10, Firefox < 101, and Firefox ESR < 91.10.
    (CVE-2022-31747)

  - A malicious website could have learned the size of a cross-origin resource that supported Range requests.
    This vulnerability affects Thunderbird < 91.10, Firefox < 101, and Firefox ESR < 91.10. (CVE-2022-31736)

  - A malicious webpage could have caused an out-of-bounds write in WebGL, leading to memory corruption and a
    potentially exploitable crash. This vulnerability affects Thunderbird < 91.10, Firefox < 101, and Firefox
    ESR < 91.10. (CVE-2022-31737)

  - When exiting fullscreen mode, an iframe could have confused the browser about the current state of
    fullscreen, resulting in potential user confusion or spoofing attacks. This vulnerability affects
    Thunderbird < 91.10, Firefox < 101, and Firefox ESR < 91.10. (CVE-2022-31738)

  - When downloading files on Windows, the % character was not escaped, which could have lead to a download
    incorrectly being saved to attacker-influenced paths that used variables such as %HOMEPATH% or
    %APPDATA%.<br>*This bug only affects Firefox for Windows. Other operating systems are unaffected.*. This
    vulnerability affects Thunderbird < 91.10, Firefox < 101, and Firefox ESR < 91.10. (CVE-2022-31739)

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