WebKit in Apple iOS before 10, Safari before 10, tvOS before 10, and watchOS before 3 allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via a crafted web site.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - WebKit in Apple iOS before 10, Safari before 10, tvOS before 10, and watchOS before 3 allows remote     attackers to execute arbitrary code or cause a denial of service (memory corruption) via a crafted web     site. (CVE-2016-4737)

Note that Nessus relies on the presence of the package as reported by the vendor.

According to its banner, the version of Apple TV on the remote device is prior to 10. It is, therefore, affected by multiple vulnerabilities in the following components :

  - Audio
  - CFNetwork
  - CoreCrypto
  - FontParser
  - IOAcceleratorFamily
  - Kernel
  - libxml2
  - libxslt
  - Security
  - WebKit

Note that only 4th generation models are affected by these vulnerabilities.

The version of Apple Safari installed on the remote Mac OS X or macOS host is prior to 10.0. It is, therefore, affected by multiple vulnerabilities :

  - Multiple memory corruption issues exist in WebKit that     allow an unauthenticated, remote attacker to cause a     denial of service condition or execute arbitrary code     via specially a crafted website. (CVE-2016-4611,     CVE-2016-4729, CVE-2016-4730, CVE-2016-4731,     CVE-2016-4734, CVE-2016-4735, CVE-2016-4737,     CVE-2016-4759, CVE-2016-4762, CVE-2016-4766,     CVE-2016-4767, CVE-2016-4768, CVE-2016-4769)

  - A cross-site scripting (XSS) vulnerability exists in the     Reader feature due to improper validation of     user-supplied input before returning it to users. 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-2016-4618)

  - A flaw exists in WebKit due to improper handling of     error prototypes. An unauthenticated, remote attacker     can exploit this, via a specially crafted website, to     execute arbitrary code. (CVE-2016-4728)

  - Multiple flaws exist in WebKit due to improper state     management. An unauthenticated, remote attacker     can exploit this, via a specially crafted website, to     cause a denial of service condition or the execution of     arbitrary code. (CVE-2016-4733, CVE-2016-4765)

  - An address bar spoofing vulnerability exists due to a     state management flaw related to sessions in tabs. An     unauthenticated, remote attacker can exploit this, via a     specially crafted website, to spoof an address in the     address bar. (CVE-2016-4751)

  - A flaw exists in WebKit due to improper handling of the     location variable. An unauthenticated, remote attacker     can exploit this, via a crafted website, to disclose     sensitive information. (CVE-2016-4758)

  - A flaw exists in WebKit that allows an unauthenticated,     remote attacker to conduct DNS rebinding attacks against     non-HTTP Safari sessions by leveraging HTTP/0.9 support.
    (CVE-2016-4760)

  - A flaw exists in WebKit in the WKWebView component due     to improper validation of X.509 certificates from HTTPS     servers. A man-in-the-middle attacker can exploit this,     via a crafted certificate, to disclose sensitive     information. (CVE-2016-4763)
