This script is Copyright (C) 2016 Tenable Network Security, Inc.


Synopsis :

The remote host has a web browser installed that is affected by
multiple vulnerabilities.

Description :

The version of Apple Safari installed on the remote Mac OS X host is
prior to 9.1.1. It is, therefore, affected by the following
vulnerabilities :

- An information disclosure vulnerability exists due to a
failure to completely delete a user's browser history
when using the 'Clear History and Website Data' action.
An attacker can exploit this to disclose sensitive
information. (CVE-2016-1849)

- Multiple memory corruption issues exist in WebKit due to
improper validation of user-supplied input. A remote
attacker, via a specially crafted website, can exploit
these issues to execute arbitrary code. (CVE-2016-1854,
CVE-2016-1855, CVE-2016-1856, CVE-2016-1857,
CVE-2016-1859)

- An information disclosure vulnerability exists in WebKit
due to insufficient taint tracking. A remote attacker
can exploit this, via a specially crafted SVG image, to
disclose information from another website.
(CVE-2016-1858)
