The remote Debian 10 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-3815 advisory.

  - A type check was missing when handling fonts in PDF.js, which would allow arbitrary JavaScript execution     in the PDF.js context. This vulnerability affects Firefox < 126, Firefox ESR < 115.11, and Thunderbird <     115.11. (CVE-2024-4367)

  - If the `browser.privatebrowsing.autostart` preference is enabled, IndexedDB files were not properly     deleted when the window was closed. This preference is disabled by default in Firefox. This vulnerability     affects Firefox < 126, Firefox ESR < 115.11, and Thunderbird < 115.11. (CVE-2024-4767)

  - A bug in popup notifications' interaction with WebAuthn made it easier for an attacker to trick a user     into granting permissions. This vulnerability affects Firefox < 126, Firefox ESR < 115.11, and Thunderbird     < 115.11. (CVE-2024-4768)

  - When importing resources using Web Workers, error messages would distinguish the difference between     `application/javascript` responses and non-script responses. This could have been abused to learn     information cross-origin. This vulnerability affects Firefox < 126, Firefox ESR < 115.11, and Thunderbird     < 115.11. (CVE-2024-4769)

  - When saving a page to PDF, certain font styles could have led to a potential use-after-free crash. This     vulnerability affects Firefox < 126, Firefox ESR < 115.11, and Thunderbird < 115.11. (CVE-2024-4770)

  - Memory safety bugs present in Firefox 125, Firefox ESR 115.10, and Thunderbird 115.10. 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 Firefox < 126, Firefox ESR < 115.11, and     Thunderbird < 115.11. (CVE-2024-4777)

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