"The version of Thunderbird installed on the remote macOS or Mac OS X host is prior to 45.8. It is, therefore, affected

  - Mozilla developers and community members Boris Zbarsky, Christian Holler, Honza Bambas, Jon Coppeard,
    Randell Jesup, Andr Bargull, Kan-Ru Chen, and Nathan Froyd reported memory safety bugs present in
    Thunderbird 45.7. 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-2017-5398)

  - Memory corruption resulting in a potentially exploitable crash during garbage collection of JavaScript due
    errors in how incremental sweeping is managed for memory cleanup. (CVE-2017-5410)

  - 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.");
