The remote Debian 11 host has packages installed that are affected by multiple vulnerabilities as referenced in the dsa-5385 advisory.

  - Unexpected data returned from the Safe Browsing API could have led to memory corruption and a potentially     exploitable crash.  (CVE-2023-1945)

  - A website could have obscured the fullscreen notification by using a combination of     <code>window.open</code>, fullscreen requests, <code>window.name</code> assignments, and     <code>setInterval</code> calls. This could have led to user confusion and possible spoofing attacks.
    (CVE-2023-29533)

  - Following a Garbage Collector compaction, weak maps may have been accessed before they were correctly     traced. This resulted in memory corruption and a potentially exploitable crash.  (CVE-2023-29535)

  - An attacker could cause the memory manager to incorrectly free a pointer that addresses attacker-     controlled memory, resulting in an assertion, memory corruption, or a potentially exploitable crash.
    (CVE-2023-29536)

  - When handling the filename directive in the Content-Disposition header, the filename would be truncated if     the filename contained a NULL character. This could have led to reflected file download attacks     potentially tricking users to install malware.  (CVE-2023-29539)

  - Firefox did not properly handle downloads of files ending in <code>.desktop</code>, which can be     interpreted to run attacker-controlled commands.  This bug only affects Firefox for Linux on certain     Distributions. Other operating systems are unaffected, and Mozilla is unable to enumerate all affected     Linux Distributions.  (CVE-2023-29541)

  - A wrong lowering instruction in the ARM64 Ion compiler resulted in a wrong optimization result.
    (CVE-2023-29548)

  - Mozilla developers Randell Jesup, Andrew Osmond, Sebastian Hengst, Andrew McCreight, and the Mozilla     Fuzzing Team reported memory safety bugs present in Firefox 111 and Firefox ESR 102.9. 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.  (CVE-2023-29550)

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