"The version of Apple Safari installed on the remote Mac OS X host is
prior to 6.2.7 / 7.1.7 / 8.0.7. It is, therefore, affected by the
following vulnerabilities :

  - A flaw exists in WebKit Page Loading due to the Origin
    request header being preserved for cross-origin
    redirects. A remote attacker can exploit this, via a
    specially crafted web page, to circumvent cross-site
    request forgery (XSRF) protections. (CVE-2015-3658)

  - A flaw exists in the WebKit Storage's SQLite authorizer
    due to insufficient comparison. A remote attacker can
    exploit this, via a specially crafted web page, to
    invoke arbitrary SQL functions, resulting in a denial
    of service condition or executing arbitrary code.
    (CVE-2015-3659)

  - An information disclosure vulnerability exists in WebKit
    PDF due to improper restrictions, related to JavaScript
    execution, of links embedded in PDF files. A remote
    attacker can exploit this, via a specially crafted PDF
    file, to disclose sensitive information from the file
    system, including cookies. (CVE-2015-3660)

  - An information disclosure vulnerability exists in WebKit
    due to improper restrictions on renaming WebSQL tables.
    A remote attacker can exploit this, via a specially
    crafted website, to access WebSQL databases belonging to
    other websites. (CVE-2015-3727)");
