The version of firefox installed on the remote host is prior to 115.13.0-1. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2FIREFOX-2024-027 advisory.

    A heap overflow vulnerability exists in libvpx - Encoding a frame that has larger dimensions than the     originally configured size with VP9 may result in a heap overflow in libvpx.We recommend upgrading to     version 1.13.1 or above (CVE-2023-6349)

    By monitoring the time certain operations take, an attacker could have guessed which external protocol     handlers were functional on a user's system. This vulnerability affects Firefox < 127, Firefox ESR <     115.12, and Thunderbird < 115.12. (CVE-2024-5690)

    By manipulating the text in an `<input>` tag, an attacker could have caused corrupt memory leading     to a potentially exploitable crash. This vulnerability affects Firefox < 127 and Firefox ESR < 115.12.
    (CVE-2024-5696)

    A race condition could lead to a cross-origin container obtaining permissions of the top-level origin.
    This vulnerability affects Firefox < 128 and Firefox ESR < 115.13. (CVE-2024-6601)

    A mismatch between allocator and deallocator could have lead to memory corruption. This vulnerability     affects Firefox < 128 and Firefox ESR < 115.13. (CVE-2024-6602)

    In an out-of-memory scenario an allocation could fail but free would have been called on the pointer     afterwards leading to memory corruption. This vulnerability affects Firefox < 128 and Firefox ESR <     115.13. (CVE-2024-6603)

    Memory safety bugs present in Firefox 127, Firefox ESR 115.12, and Thunderbird 115.12. 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 < 128 and Firefox ESR < 115.13.
    (CVE-2024-6604)
