The remote Ubuntu 18.04 LTS / 20.04 LTS / 21.10 host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-5345-1 advisory.

  - If a document created a sandboxed iframe without <code>allow-scripts</code>, and subsequently appended an     element to the iframe's document that e.g. had a JavaScript event handler - the event handler would have     run despite the iframe's sandbox. This vulnerability affects Firefox < 97, Thunderbird < 91.6, and Firefox     ESR < 91.6. (CVE-2022-22759)

  - It may be possible for an attacker to craft an email message that causes Thunderbird to perform an out-of-     bounds write of one byte when processing the message. This vulnerability affects Thunderbird < 91.6.1.
    (CVE-2022-0566)

  - If a user installed an extension of a particular type, the extension could have auto-updated itself and     while doing so, bypass the prompt which grants the new version the new requested permissions. This     vulnerability affects Firefox < 97, Thunderbird < 91.6, and Firefox ESR < 91.6. (CVE-2022-22754)

  - If a user was convinced to drag and drop an image to their desktop or other folder, the resulting object     could have been changed into an executable script which would have run arbitrary code after the user     clicked on it. This vulnerability affects Firefox < 97, Thunderbird < 91.6, and Firefox ESR < 91.6.
    (CVE-2022-22756)

  - When importing resources using Web Workers, error messages would distinguish the difference between     <code>application/javascript</code> responses and non-script responses. This could have been abused to     learn information cross-origin. This vulnerability affects Firefox < 97, Thunderbird < 91.6, and Firefox     ESR < 91.6. (CVE-2022-22760)

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