"The version of firefox installed on the remote host is prior to 115.10.0-1. It is, therefore, affected by multiple
vulnerabilities as referenced in the ALAS2FIREFOX-2024-024 advisory.

  - An attacker was able to inject an event handler into a privileged object that would allow arbitrary
    JavaScript execution in the parent process. Note: This vulnerability affects Desktop Firefox only, it does
    not affect mobile versions of Firefox. This vulnerability affects Firefox < 124.0.1 and Firefox ESR <
    115.9.1. (CVE-2024-29944)

  - 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)

  - 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)

  - 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)

  - 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)

  - 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)

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