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)
