"The version of Firefox ESR installed on the remote macOS or Mac OS X host is prior to 115.20. It is, therefore, affected
by multiple vulnerabilities as referenced in the mfsa2025-08 advisory.

  - Memory safety bugs present in Firefox 134, Thunderbird 134, Firefox ESR 115.19, Firefox ESR 128.6,
    Thunderbird 115.19, and Thunderbird 128.6. 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-2025-1016)

  - An attacker could have caused a use-after-free via crafted XSLT data, leading to a potentially exploitable
    crash. (CVE-2025-1009)

  - An attacker could have caused a use-after-free via the Custom Highlight API, leading to a potentially
    exploitable crash. (CVE-2025-1010)

  - A race during concurrent delazification could have led to a use-after-free. (CVE-2025-1012)

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