"The version of Thunderbird installed on the remote macOS or Mac OS X host is prior to 68.6. It is, therefore, affected
by multiple vulnerabilities as referenced in the mfsa2020-10 advisory.

  - Mozilla developers Byron Campen, Jason Kratzer, and Christian Holler reported memory safety bugs present
    in Thunderbird 68.5. 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-2020-6814)

  - When removing data about an origin whose tab was recently closed, a use-after-free could occur in the
    Quota manager, resulting in a potentially exploitable crash. (CVE-2020-6805)

  - By carefully crafting promise resolutions, it was possible to cause an out-of-bounds read off the end of
    an array resized during script execution. This could have led to memory corruption and a potentially
    exploitable crash. (CVE-2020-6806)

  - When a device was changed while a stream was about to be destroyed, the <code>stream-reinit</code> task
    may have been executed after the stream was destroyed, causing a use-after-free and a potentially
    exploitable crash. (CVE-2020-6807)

  - The 'Copy as cURL' feature of Devtools' network tab did not properly escape the HTTP method of a request,
    which can be controlled by the website. If a user used the 'Copy as Curl' feature and pasted the command
    into a terminal, it could have resulted in command injection and arbitrary command execution.
    (CVE-2020-6811)

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