The remote Ubuntu 16.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-3079-1 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 the remote Apple TV device is prior to 9.2.1. It is, therefore, affected by multiple vulnerabilities in the following components :

  - CFNetwork Proxies
  - CommonCrypto
  - CoreCapture
  - Disk Images
  - ImageIO
  - IOAcceleratorFamily
  - IOHIDFamily
  - Kernel
  - libc
  - libxml2
  - libxslt
  - OpenGL
  - WebKit
  - WebKit Canvas

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

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

  - WebKit, as used in Apple iOS before 9.3.2, Safari before 9.1.1, and tvOS before 9.2.1, 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-2016-1855, CVE-2016-1856, and CVE-2016-1857. (CVE-2016-1854)

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

The mobile device is running a version of iOS prior to 9.3.2. It is, therefore, affected by multiple vulnerabilities in the following components :

  - Accessibility
  - CFNetwork Proxies
  - CommonCrypto
  - CoreCapture
  - Disk Images
  - ImageIO
  - IOAcceleratorFamily
  - IOHIDFamily
  - Kernel
  - libc
  - libxml2
  - libxslt
  - MapKit
  - OpenGL
  - Safari
  - Siri
  - WebKit
  - WebKit Canvas

The version of Apple Safari installed on the remote Mac OS X host is prior to 9.1.1. It is, therefore, affected by the following vulnerabilities :

  - An information disclosure vulnerability exists due to a     failure to completely delete a user's browser history     when using the 'Clear History and Website Data' action.
    An attacker can exploit this to disclose sensitive     information. (CVE-2016-1849)

  - Multiple memory corruption issues exist in WebKit due to     improper validation of user-supplied input. A remote     attacker, via a specially crafted website, can exploit     these issues to execute arbitrary code. (CVE-2016-1854,     CVE-2016-1855, CVE-2016-1856, CVE-2016-1857,     CVE-2016-1859)

  - An information disclosure vulnerability exists in WebKit     due to insufficient taint tracking. A remote attacker     can exploit this, via a specially crafted SVG image, to     disclose information from another website.
    (CVE-2016-1858)

Versions of Apple TV earlier than 9.2.1 are unpatched for vulnerabilities in the following components :

 - CFNetwork Proxies
 - CommonCrypto
 - CoreCapture
 - Disk Images
 - ImageIO
 - IOAcceleratorFamily
 - IOHIDFamily
 - Kernel
 - libc
 - libxml2
 - libxslt
 - OpenGL
 - WebKit
 - WebKit Canvas
