The remote Debian 11 / 12 host has packages installed that are affected by multiple vulnerabilities as referenced in the dsa-5663 advisory.

  - The permission prompt input delay could expire while the window is not in focus. This makes it vulnerable     to clickjacking by malicious websites. This vulnerability affects Firefox < 124 and Firefox ESR < 115.10.
    (CVE-2024-2609)

  - There was no limit to the number of HTTP/2 CONTINUATION frames that would be processed. A server could     abuse this to create an Out of Memory condition in the browser. This vulnerability affects Firefox < 125     and Firefox ESR < 115.10. (CVE-2024-3302)

  - GetBoundName could return the wrong version of an object when JIT optimizations were applied. This     vulnerability affects Firefox < 125 and Firefox ESR < 115.10. (CVE-2024-3852)

  - In some code patterns the JIT incorrectly optimized switch statements and generated code with out-of-     bounds-reads. This vulnerability affects Firefox < 125 and Firefox ESR < 115.10. (CVE-2024-3854)

  - The JIT created incorrect code for arguments in certain cases. This led to potential use-after-free     crashes during garbage collection. This vulnerability affects Firefox < 125 and Firefox ESR < 115.10.
    (CVE-2024-3857)

  - On 32-bit versions there were integer-overflows that led to an out-of-bounds-read that potentially could     be triggered by a malformed OpenType font. This vulnerability affects Firefox < 125 and Firefox ESR <     115.10. (CVE-2024-3859)

  - If an AlignedBuffer were assigned to itself, the subsequent self-move could result in an incorrect     reference count and later use-after-free. This vulnerability affects Firefox < 125 and Firefox ESR <     115.10. (CVE-2024-3861)

  - Memory safety bug present in Firefox 124, Firefox ESR 115.9, and Thunderbird 115.9. This bug showed     evidence of memory corruption and we presume that with enough effort this could have been exploited to run     arbitrary code. This vulnerability affects Firefox < 125 and Firefox ESR < 115.10. (CVE-2024-3864)

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