  - An information disclosure vulnerability exists in the

    An unauthenticated, remote attacker can exploit this,
    via a timing side-channel attack, to disclose sensitive
    cross-domain information. (CVE-2017-7006)

  - An unspecified flaw exists that allows an
    unauthenticated, remote attacker to spoof the address
    bar via a specially crafted website. (CVE-2017-7011)

  - Multiple memory corruption issues exists in the 'WebKit
    Web Inspector' component due to improper validation of
    input. An unauthenticated, remote attacker can exploit
    these issues, via a specially crafted web page, to
    execute arbitrary code. (CVE-2017-7012)

  - Multiple cross-site scripting (XSS) vulnerabilities
    exist in the WebKit component in the DOMParser due to
    improper validation of user-supplied input before
    returning it to users. An unauthenticated, remote
    attacker can exploit these issue, via a specially
    crafted URL, to execute arbitrary script code in a
    user's browser session. (CVE-2017-7038, CVE-2017-7059)

  - A denial of service vulnerability exists in the Safari
    Printing component. An unauthenticated, remote attacker
    can exploit this, via a specially crafted web page, to
    create an infinite number of print dialogs.
    (CVE-2017-7060)

  - An unspecified memory initialization flaw exists in
    WebKit. A local attacker can exploit this, via a
    specially crafted application, to disclose restricted

Impact :

    A remote attacker could execute arbitrary code, cause a Denial of

      timing side-channel attack to bypass the Same Origin Policy, obtain
      sensitive information, or spoof the address bar.
