The version of Thunderbird installed on the remote macOS or Mac OS X host is prior to 60.5. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2019-03 advisory.

  - A use-after-free vulnerability can occur while parsing     an HTML5 stream in concert with custom HTML elements.
    This results in the stream parser object being freed     while still in use, leading to a potentially exploitable     crash. (CVE-2018-18500)

  - An earlier fix for an Inter-process Communication (IPC)     vulnerability, CVE-2011-3079, added authentication to     communication between IPC endpoints and server parents     during IPC process creation. This authentication is     insufficient for channels created after the IPC process     is started, leading to the authentication not being     correctly applied to later channels. This could allow     for a sandbox escape through IPC channels due to lack of     message validation in the listener process.
    (CVE-2018-18505)

  - A vulnerability in the Libical libary used by     Thunderbird can allow remote attackers to cause a denial     of service (use-after-free) via a crafted ICS calendar     file. (CVE-2016-5824)

  - Mozilla developers and community members Alex Gaynor,     Christoph Diehl, Steven Crane, Jason Kratzer, Gary     Kwong, and Christian Holler reported memory safety bugs     present in Firefox 64, Firefox ESR 60.4, and Thunderbird     60.4. Some of these bugs showed evidence of memory     corruption and we presume that with enough effort that     some of these could be exploited to run arbitrary code.
    (CVE-2018-18501)

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