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

The version of Firefox ESR installed on the remote Windows host is prior to 128.6. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2025-02 advisory.

  - Memory safety bugs present in Firefox 133, Thunderbird 133, Firefox ESR 115.18, Firefox ESR 128.5,     Thunderbird 115.18, and Thunderbird 128.5. 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-2025-0242)

  - When segmenting specially crafted text, segmentation would corrupt memory leading to a potentially     exploitable crash. (CVE-2025-0241)

  - The WebChannel API, which is used to transport various information across processes, did not check the     sending principal but rather accepted the principal being sent. This could have led to privilege     escalation attacks. (CVE-2025-0237)

  - Assuming a controlled failed memory allocation, an attacker could have caused a use-after-free, leading to     a potentially exploitable crash. (CVE-2025-0238)

  - When using Alt-Svc, ALPN did not properly validate certificates when the original server is redirecting to     an insecure site. (CVE-2025-0239)

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