"The version of Google Chrome installed on the remote macOS host is
prior to 71.0.3578.98. It is, therefore, affected by a use after free
vulnerability in pdfium. This could allow a remote attacker to
potentially exploit heap corruption via a crafted pdf file as noted
in Google Chrome stable channel update release notes for 2018/12/12.
Please refer to the release notes for additional information.

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