"The version of Thunderbird installed on the remote macOS or Mac OS X host is prior to 151.0. It is, therefore, affected
by multiple vulnerabilities as referenced in the mfsa2026-50 advisory.

  - Memory safety bugs present in Thunderbird 140.10 and Thunderbird 150. 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-2026-8974, CVE-2026-8975)

  - Incorrect boundary conditions in the Audio/Video: Web Codecs component. This vulnerability was fixed in
    Firefox 151, Firefox ESR 115.36, Firefox ESR 140.11, Thunderbird 151, and Thunderbird 140.11.
    (CVE-2026-8946)

  - Use-after-free in the DOM: Bindings (WebIDL) component. This vulnerability was fixed in Firefox 151,
    Firefox ESR 115.36, Firefox ESR 140.11, Thunderbird 151, and Thunderbird 140.11. (CVE-2026-8947)

  - Same-origin policy bypass in the DOM: Networking component. This vulnerability was fixed in Firefox 151
    and Thunderbird 151. (CVE-2026-8948)

  - Integer overflow in the Widget: Win32 component. This vulnerability was fixed in Firefox 151, Firefox ESR
    140.11, Thunderbird 151, and Thunderbird 140.11. (CVE-2026-8949)

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