The remote Ubuntu 16.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-3166-1 advisory.

    A large number of security issues were discovered in the WebKitGTK+ Web and JavaScript engines. If a user     were tricked into viewing a malicious website, a remote attacker could exploit a variety of issues related     to web browser security, including cross-site scripting attacks, denial of service attacks, and arbitrary     code execution.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

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

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)
