The version of Thunderbird installed on the remote Windows host is prior to 52.0. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2017-09 advisory.

  - Mozilla developers and community members Carsten Book, Calixte Denizet, Christian Holler, Andrew     McCreight, David Bolter, David Keeler, Jon Coppeard, Tyson Smith, Ronald Crane, Tooru Fujisawa, Ben Kelly,     Bob Owen, Jed Davis, Julian Seward, Julian Hector, Philipp, Markus Stange, and  Andr Bargull reported     memory safety bugs present in Firefox 51. 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-2017-5399)

  - A segmentation fault can occur during some bidirectional layout operations. (CVE-2017-5413)

  - JIT-spray targeting asm.js combined with a heap spray allows for a bypass of ASLR and DEP protections     leading to potential memory corruption attacks. (CVE-2017-5400)

  - A crash triggerable by web content in which an <code>ErrorResult</code> references unassigned memory due     to a logic error. The resulting crash may be exploitable. (CVE-2017-5401)

  - A use-after-free can occur when events are fired for a <code>FontFace</code> object after the object has     been already been destroyed while working with fonts. This results in a potentially exploitable crash.
    (CVE-2017-5402)

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