The remote Debian 10 / 11 host has packages installed that are affected by multiple vulnerabilities as referenced in the dsa-5158 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)

  - An attacker could have sent a message to the parent process where the contents were used to double-index     into a JavaScript object, leading to prototype pollution and ultimately attacker-controlled JavaScript     executing in the privileged parent process. This vulnerability affects Firefox ESR < 91.9.1, Firefox <     100.0.2, Firefox for Android < 100.3.0, and Thunderbird < 91.9.1. (CVE-2022-1529)

  - If an attacker was able to corrupt the methods of an Array object in JavaScript via prototype pollution,     they could have achieved execution of attacker-controlled JavaScript code in a privileged context. This     vulnerability affects Firefox ESR < 91.9.1, Firefox < 100.0.2, Firefox for Android < 100.3.0, and     Thunderbird < 91.9.1. (CVE-2022-1802)

  - When displaying the sender of an email, and the sender name contained the Braille Pattern Blank space     character multiple times, Thunderbird would have displayed all the spaces. This could have been used by an     attacker to send an email message with the attacker's digital signature, that was shown with an arbitrary     sender email address chosen by the attacker. If the sender name started with a false email address,     followed by many Braille space characters, the attacker's email address was not visible. Because     Thunderbird compared the invisible sender address with the signature's email address, if the signing key     or certificate was accepted by Thunderbird, the email was shown as having a valid digital signature. This     vulnerability affects Thunderbird < 91.10. (CVE-2022-1834)

  - 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)

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