The remote Debian 10 / 11 host has packages installed that are affected by multiple vulnerabilities as referenced in the dsa-5106 advisory.

  - If an attacker could control the contents of an iframe sandboxed with <code>allow-popups</code> but not     <code>allow-scripts</code>, they were able to craft a link that, when clicked, would lead to JavaScript     execution in violation of the sandbox. This vulnerability affects Firefox < 98, Firefox ESR < 91.7, and     Thunderbird < 91.7. (CVE-2022-26384)

  - An attacker could have caused a use-after-free by forcing a text reflow in an SVG object leading to a     potentially exploitable crash. This vulnerability affects Firefox < 98, Firefox ESR < 91.7, and     Thunderbird < 91.7. (CVE-2022-26381)

  - When resizing a popup after requesting fullscreen access, the popup would not display the fullscreen     notification. This vulnerability affects Firefox < 98, Firefox ESR < 91.7, and Thunderbird < 91.7.
    (CVE-2022-26383)

  - Previously Firefox for macOS and Linux would download temporary files to a user-specific directory in     <code>/tmp</code>, but this behavior was changed to download them to <code>/tmp</code> where they could be     affected by other local users. This behavior was reverted to the original, user-specific directory.
    <br>*This bug only affects Firefox for macOS and Linux. Other operating systems are unaffected.*. This     vulnerability affects Firefox ESR < 91.7 and Thunderbird < 91.7. (CVE-2022-26386)

  - When installing an add-on, Firefox verified the signature before prompting the user; but while the user     was confirming the prompt, the underlying add-on file could have been modified and Firefox would not have     noticed. This vulnerability affects Firefox < 98, Firefox ESR < 91.7, and Thunderbird < 91.7.
    (CVE-2022-26387)

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