The version of Firefox ESR installed on the remote macOS or Mac OS X host is prior to 91.10. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2022-21 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. (CVE-2022-31747)

  - A malicious website could have learned the size of a cross-origin resource that supported Range requests.
    (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. (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. (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%.
    This bug only affects Firefox for Windows. Other operating systems are unaffected. (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.

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.
