"The version of Apple iTunes running on the remote Windows host is
prior to 12.5.1. It is, therefore, affected by multiple
vulnerabilities :

  - A remote code execution vulnerability exists due to
    improper handling of error prototypes. An
    unauthenticated, remote attacker can exploit this, by
    convincing a user to visit a maliciously crafted
    website, to execute arbitrary code. (CVE-2016-4728)

  - An information disclosure vulnerability exists in WebKit
    due to a permission issue caused by improper handling of
    the location variable. An unauthenticated, remote
    attacker can exploit this, by convincing a user to visit
    a maliciously crafted website, to disclose sensitive
    information. (CVE-2016-4758)

  - Multiple memory corruption errors exist in WebKit due to
    improper validation of user-supplied input. An
    unauthenticated, remote attacker can exploit these
    issues, by convincing a user to visit a maliciously
    crafted website, to cause a denial of service condition
    or the execution of arbitrary code. (CVE-2016-4759,
    CVE-2016-4762, CVE-2016-4764, CVE-2016-4765,
    CVE-2016-4766, CVE-2016-4767, CVE-2016-4768,
    CVE-2016-4769)

  - A rebinding flaw exists in WebKit due to a failure to
    restrict HTTP/0.9 responses to default ports and
    cancel resource loads if a document is loaded with a
    different HTTP protocol version. An unauthenticated,
    remote attacker can exploit this, by convincing a user
    to visit a maliciously crafted website, to access
    non-HTTP services. (CVE-2016-4760)

  - A security bypass vulnerability exists in WebKit in the
    WKWebView component due to a failure to properly verify
    X.509 certificates from HTTPS servers. A
    man-in-the-middle attacker can exploit this, via a
    specially crafted certificate, to spoof servers and
    disclose or manipulate network traffic. (CVE-2016-4763)

Note that Nessus has not tested for these issues but has instead
relied only on the application's self-reported version number.");
