"The version of Thunderbird installed on the remote macOS or Mac OS X host is prior to 78.10.2. It is, therefore,
affected by multiple vulnerabilities as referenced in the mfsa2021-22 advisory.

  - If a MIME encoded email contains an OpenPGP inline signed or encrypted message part, but also contains an
    additional unprotected part, Thunderbird did not indicate that only parts of the message are protected.
    (CVE-2021-29957)

  - OpenPGP secret keys that were imported using Thunderbird version 78.8.1 up to version 78.10.1 were stored
    unencrypted on the user's local disk. The master password protection was inactive for those keys. Version
    78.10.2 will restore the protection mechanism for newly imported keys, and will automatically protect keys
    that had been imported using affected Thunderbird versions. (CVE-2021-29956)

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