"The version of Thunderbird installed on the remote macOS or Mac OS X host is prior to 78.14. It is, therefore, affected
by multiple vulnerabilities as referenced in the mfsa2021-42 advisory.

  - When delegating navigations to the operating system, Thunderbird would accept the `mk` scheme which might
    allow attackers to launch pages and execute scripts in Internet Explorer in unprivileged mode. This
    bug only affects Thunderbird for Windows. Other operating systems are unaffected. (CVE-2021-38492)

  - Mozilla developers Tyson Smith and Gabriele Svelto reported memory safety bugs present in Thunderbird
    78.13. 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-2021-38493)

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