The remote Ubuntu 16.04 LTS / 18.04 LTS / 20.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-4373-1 advisory.

    Multiple security issues were discovered in Thunderbird. If a user were tricked in to opening a specially     crafted website in a browsing context, an attacker could potentially exploit these to cause a denial of     service, or execute arbitrary code. (CVE-2020-6831, CVE-2020-12387, CVE-2020-12395)

    It was discovered that the Devtools Copy as cURL feature did not properly escape the HTTP POST     data of a request. If a user were tricked in to using the Copy as cURL feature to copy and paste a     command with specially crafted data in to a terminal, an attacker could potentially exploit this to obtain     sensitive information from local files. (CVE-2020-12392)

    It was discovered that Thunderbird did not correctly handle Unicode whitespace characters within the From     email header. An attacker could potentially exploit this to spoof the sender email address that     Thunderbird displays. (CVE-2020-12397)

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

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