"The remote Ubuntu 16.04 LTS / 18.04 LTS host has packages installed that are affected by a vulnerability as referenced
in the USN-3998-1 advisory.

    Marcus Brinkmann discovered that Evolution Data Server did not correctly interpret the output from GPG
    when decrypting encrypted messages. Under certain circumstances, this could result in displaying clear-
    text portions of encrypted messages as though they were encrypted.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

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