WebKit in Apple iOS before 10, tvOS before 10, iTunes before 12.5.1 on Windows, and Safari before 10 allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via a crafted web site, a different vulnerability than CVE-2016-4759, CVE-2016-4765, CVE-2016-4767, and CVE-2016-4768.

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.
