"The version of Thunderbird installed on the remote macOS or Mac OS X host is prior to 45.7. It is, therefore, affected
by multiple vulnerabilities as referenced in the mfsa2017-03 advisory.

  - A use-after-free vulnerability in the Media Decoder when working with media files when some events are
    fired after the media elements are freed from memory. (CVE-2017-5396)

  - JIT code allocation can allow for a bypass of ASLR and DEP protections leading to potential memory
    corruption attacks. (CVE-2017-5375)

  - Use-after-free while manipulating XSL in XSLT documents (CVE-2017-5376)

  - Hashed codes of JavaScript objects are shared between pages. This allows for pointer leaks because an
    objects address can be discovered through hash codes, and also allows for data leakage of an objects
    content using these hash codes. (CVE-2017-5378)

  - A potential use-after-free found through fuzzing during DOM manipulation of SVG content. (CVE-2017-5380)

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