"The version of Apple Safari installed on the remote Mac OS X host is
prior to 6.2.8 / 7.1.8 / 8.0.8. It is, therefore, affected by the
following vulnerabilities :

  - An unspecified flaw exists that allows an attacker to
    spoof UI elements by using crafted web pages.
    (CVE-2015-3729)

  - Multiple memory corruption flaws exist in WebKit due
    to improper validation of user-supplied input. An
    attacker can exploit these, by using a crafted web page,
    to execute arbitrary code. (CVE-2015-3730, CVE-2015-3731
    CVE-2015-3732, CVE-2015-3733, CVE-2015-3734,

    CVE-2015-3747, CVE-2015-3748, CVE-2015-3749)

  - A security policy bypass vulnerability exists in WebKit
    related to handling Content Security Policy report
    requests. An attacker can exploit this to bypass the
    HTTP Strict Transport Security policy. (CVE-2015-3750)

  - A security policy bypass vulnerability exists in WebKit
    that allows websites to use video controls to load
    images nested in object elements in violation of Content
    Security Policy directives. (CVE-2015-3751)

  - An information disclosure vulnerability exists in WebKit
    related to how cookies are added to Content Security
    Policy report requests, which results in cookies being
    exposed to cross-origin requests. Also, cookies set
    during regular browsing are sent during private
    browsing. (CVE-2015-3752)

  - An information disclosure vulnerability exists in the
    WebKit Canvas component when images are called using
    URLs that redirect to a data:image resource. An
    attacker, using a malicious website, can exploit this to
    disclose image data cross-origin. (CVE-2015-3753)

  - An information disclosure vulnerability exists in WebKit
    page loading where the caching of HTTP authentication
    credentials entered in private browsing mode were carried
    over into regular browsing, resulting in a user's private
    browsing history being exposed. (CVE-2015-3754)

  - A flaw in the WebKit process model allows a malicious
    website to display an arbitrary URL, which can allow
    user interface spoofing. (CVE-2015-3755)");
