"The version of Firefox ESR installed on the remote macOS or Mac OS X
host is prior to 60.5.1. It is, therefore, affected by multiple
vulnerabilities as referenced in the mfsa2019-05 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)

  - A buffer overflow vulnerability in the Skia library can
    occur with Canvas 2D acceleration on macOS. This issue
    was addressed by disabling Canvas 2D acceleration in
    Firefox ESR. *Note: this does not affect other
    versions and platforms where Canvas 2D acceleration is
    already disabled by default.* (CVE-2018-18335)

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