The remote Fedora 39 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2024-121f5cec9f advisory.

  - 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,     Firefox ESR < 115.10, and Thunderbird < 115.10. (CVE-2024-3302)

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

  - A use-after-free could result if a JavaScript realm was in the process of being initialized when a garbage     collection started. This vulnerability affects Firefox < 125. (CVE-2024-3853)

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

  - In certain cases the JIT incorrectly optimized MSubstr operations, which led to out-of-bounds reads. This     vulnerability affects Firefox < 125. (CVE-2024-3855)

  - A use-after-free could occur during WASM execution if garbage collection ran during the creation of an     array. This vulnerability affects Firefox < 125. (CVE-2024-3856)

  - 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, Firefox ESR < 115.10, and     Thunderbird < 115.10. (CVE-2024-3857)

  - It was possible to mutate a JavaScript object so that the JIT could crash while tracing it. This     vulnerability affects Firefox < 125. (CVE-2024-3858)

  - 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, Firefox ESR < 115.10,     and Thunderbird < 115.10. (CVE-2024-3859)

  - An out-of-memory condition during object initialization could result in an empty shape list. If the JIT     subsequently traced the object it would crash. This vulnerability affects Firefox < 125. (CVE-2024-3860)

  - 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, Firefox ESR < 115.10,     and Thunderbird < 115.10. (CVE-2024-3861)

  - The MarkStack assignment operator, part of the JavaScript engine, could access uninitialized memory if it     were used in a self-assignment. This vulnerability affects Firefox < 125. (CVE-2024-3862)

  - The executable file warning was not presented when downloading .xrm-ms files. *Note: This issue only     affected Windows operating systems. Other operating systems are unaffected.* This vulnerability affects     Firefox < 125, Firefox ESR < 115.10, and Thunderbird < 115.10. (CVE-2024-3863)

  - 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, Firefox ESR < 115.10, and Thunderbird < 115.10.
    (CVE-2024-3864)

  - Memory safety bugs present in Firefox 124. 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 < 125. (CVE-2024-3865)

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