  - Multiple remote code execution vulnerabilities exist in
    WebKit due to improper validation of user-supplied
    input and improper handling of objects in memory. An
    unauthenticated, remote attacker can exploit these
    vulnerabilities, by convincing a user to visit a
    specially crafted website, to corrupt memory and execute
    arbitrary code. (CVE-2016-4692, CVE-2016-7635,
    CVE-2016-7652)

  - Multiple information disclosure vulnerabilities exist
    in WebKit due to improper validation of user-supplied
    input. An unauthenticated, remote attacker can exploit
    these, by convincing a user to visit a specially crafted
    website, to disclose memory contents. (CVE-2016-4743,
    CVE-2016-7656)

  - An information disclosure vulnerability exists in WebKit
    due to improper validation of user-supplied input. An
    unauthenticated, remote attacker can exploit this, by
    convincing a user to visit a specially crafted website,
    to disclose user information. (CVE-2016-7586)

  - Multiple remote code execution vulnerabilities exist in
    WebKit due to improper validation of user-supplied
    input and improper state management. An unauthenticated,
    remote attacker can exploit these vulnerabilities, by
    convincing a user to visit a specially crafted website,
    to corrupt memory and execute arbitrary code.

  - An information disclosure vulnerability exists in WebKit
    due to improper handling of JavaScript prompts. An
    unauthenticated, remote attacker can exploit this, by
    convincing a user to visit a specially crafted website,
    to corrupt memory and execute arbitrary code.
    (CVE-2016-7592)

  - An information disclosure vulnerability exists in WebKit
    due to the use of uninitialized memory. An
    unauthenticated, remote attacker can exploit this, by
    convincing a user to visit a specially crafted website,
    to disclose memory contents. (CVE-2016-7598)

  - An information disclosure vulnerability exists that is
    triggered when handling HTTP redirections. An
    unauthenticated, remote attacker can exploit this, by
    convincing a user to visit a specially crafted website,
    to disclose user information. (CVE-2016-7599)

  - An information disclosure vulnerability exists in WebKit
    due to improper validation of user-supplied input and
    blob URLs. An unauthenticated, remote attacker can
    exploit this, via a specially crafted blob URL, to
    disclose user information. (CVE-2016-7623)

  - A remote code execution vulnerability exists in WebKit
    due to improper validation of user-supplied
    input and improper state management. An unauthenticated,
    remote attacker can exploit this, by convincing a user
    to visit a specially crafted website, to cause a denial
    of service condition or the execution of arbitrary code.
    (CVE-2016-7632)

  - A cross-site scripting (XSS) vulnerability exists in
    Safari Reader due to improper validation of
    user-supplied input. An unauthenticated, remote attacker
    can exploit this, by convincing a user to follow a
    specially crafted link, to execute arbitrary script code
    in a user's browser session. (CVE-2016-7650)");
