The version of Firefox installed on the remote macOS or Mac OS X host is prior to 142.0. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2025-64 advisory.

  - Memory safety bugs present in Firefox 141 and Thunderbird 141. 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-2025-9187)

  - An attacker was able to perform memory corruption in the GMP process which processes encrypted media. This     process is also heavily sandboxed, but represents slightly different privileges from the content process.
    (CVE-2025-9179)

  - Same-origin policy bypass in the Graphics: Canvas2D component. (CVE-2025-9180)

  - Uninitialized memory in the JavaScript Engine component. (CVE-2025-9181)

  - Spoofing issue in the Address Bar component of Firefox Focus for Android. (CVE-2025-9186)

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