"The version of Apple iTunes installed on the remote Windows host is
prior to 12.5.4. It is, therefore, affected by multiple
vulnerabilities :

  - 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.

    CVE-2016-7654)

  - 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)

  - 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.
