"The version of Apple Safari installed on the remote Mac OS X host is
prior to 9.0.3. It is, therefore, affected by the following
vulnerabilities :

  - Multiple memory corruption vulnerabilities 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 or cause a denial of service. (CVE-2016-1723,
    CVE-2016-1724, CVE-2016-1725, CVE-2016-1726,
    CVE-2016-1727)

  - A flaw exists in the Cascading Style Sheets (CSS)
    implementation in WebKit CSS when handling the
    'a:visited button' CSS selector while evaluating the
    height of the containing element. A remote attacker
    can exploit this, via a crafted website, to obtain
    sensitive browser history information. (CVE-2016-1728)");
