"The version of Firefox installed on the remote macOS or Mac OS X host
is prior to 65.0.1. It is, therefore, affected by multiple
vulnerabilities as referenced in the mfsa2019-04 advisory.

  - A use-after-free vulnerability in the Skia library can
    occur when creating a path, leading to a potentially
    exploitable crash. (CVE-2018-18356)

  - An integer overflow vulnerability in the Skia library
    can occur after specific transform operations, leading
    to a potentially exploitable crash. (CVE-2019-5785)

  - Cross-origin images can be read from a
    canvas element in violation of the same-
    origin policy using the
    transferFromImageBitmap method.  *Note:
    This only affects Firefox 65. Previous versions are
    unaffected.* (CVE-2018-18511)

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