The remote Debian 11 / 12 host has packages installed that are affected by multiple vulnerabilities as referenced in the dsa-5581 advisory.

  - The WebGL `DrawElementsInstanced` method was susceptible to a heap buffer overflow when used on systems     with the Mesa VM driver. This issue could allow an attacker to perform remote code execution and sandbox     escape. This vulnerability affects Firefox ESR < 115.6, Thunderbird < 115.6, and Firefox < 121.
    (CVE-2023-6856)

  - When resolving a symlink, a race may occur where the buffer passed to `readlink` may actually be smaller     than necessary. *This bug only affects Firefox on Unix-based operating systems (Android, Linux, MacOS).
    Windows is unaffected.* This vulnerability affects Firefox ESR < 115.6, Thunderbird < 115.6, and Firefox <     121. (CVE-2023-6857)

  - Firefox was susceptible to a heap buffer overflow in `nsTextFragment` due to insufficient OOM handling.
    This vulnerability affects Firefox ESR < 115.6, Thunderbird < 115.6, and Firefox < 121. (CVE-2023-6858)

  - A use-after-free condition affected TLS socket creation when under memory pressure. This vulnerability     affects Firefox ESR < 115.6, Thunderbird < 115.6, and Firefox < 121. (CVE-2023-6859)

  - The `VideoBridge` allowed any content process to use textures produced by remote decoders. This could be     abused to escape the sandbox. This vulnerability affects Firefox ESR < 115.6, Thunderbird < 115.6, and     Firefox < 121. (CVE-2023-6860)

  - The `nsWindow::PickerOpen(void)` method was susceptible to a heap buffer overflow when running in headless     mode. This vulnerability affects Firefox ESR < 115.6, Thunderbird < 115.6, and Firefox < 121.
    (CVE-2023-6861)

  - A use-after-free was identified in the `nsDNSService::Init`. This issue appears to manifest rarely during     start-up. This vulnerability affects Firefox ESR < 115.6 and Thunderbird < 115.6. (CVE-2023-6862)

  - The `ShutdownObserver()` was susceptible to potentially undefined behavior due to its reliance on a     dynamic type that lacked a virtual destructor. This vulnerability affects Firefox ESR < 115.6, Thunderbird     < 115.6, and Firefox < 121. (CVE-2023-6863)

  - Memory safety bugs present in Firefox 120, Firefox ESR 115.5, and Thunderbird 115.5. 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 ESR < 115.6, Thunderbird < 115.6, and     Firefox < 121. (CVE-2023-6864)

  - `EncryptingOutputStream` was susceptible to exposing uninitialized data. This issue could only be abused     in order to write data to a local disk which may have implications for private browsing mode. This     vulnerability affects Firefox ESR < 115.6 and Firefox < 121. (CVE-2023-6865)

  - The timing of a button click causing a popup to disappear was approximately the same length as the anti-     clickjacking delay on permission prompts. It was possible to use this fact to surprise users by luring     them to click where the permission grant button would be about to appear. This vulnerability affects     Firefox ESR < 115.6 and Firefox < 121. (CVE-2023-6867)

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