"The version of Firefox ESR installed on the remote macOS or Mac OS X host is prior to 52.6. It is, therefore, affected
by multiple vulnerabilities as referenced in the mfsa2018-03 advisory.

  - A use-after-free vulnerability can occur during font face manipulation when a font face is freed while
    still in use, resulting in a potentially exploitable crash. (CVE-2018-5104)

  - A use-after-free vulnerability can occur during WebRTC connections when interacting with the DTMF timers.
    This results in a potentially exploitable crash. (CVE-2018-5091)

  - An integer overflow vulnerability in the Skia library when allocating memory for edge builders on some
    systems with at least 8 GB of RAM. This results in the use of uninitialized memory, resulting in a
    potentially exploitable crash. (CVE-2018-5095)

  - A use-after-free vulnerability can occur while editing events in form elements on a page, resulting in a
    potentially exploitable crash. (CVE-2018-5096)

  - A use-after-free vulnerability can occur during XSL transformations when the source document for the
    transformation is manipulated by script content during the transformation. This results in a potentially
    exploitable crash. (CVE-2018-5097)

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