Cross-site scripting (XSS) vulnerability in the WebKit JavaScript bindings in Apple iOS before 9.3.3 and Safari before 9.1.2 allows remote attackers to inject arbitrary web script or HTML via a crafted HTTP/0.9 response, related to a "cross-protocol cross-site scripting (XPXSS)" vulnerability.

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

  - Cross-site scripting (XSS) vulnerability in the WebKit JavaScript bindings in Apple iOS before 9.3.3 and     Safari before 9.1.2 allows remote attackers to inject arbitrary web script or HTML via a crafted HTTP/0.9     response, related to a cross-protocol cross-site scripting (XPXSS) vulnerability. (CVE-2016-4651)

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

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.

The version of Safari installed on the remote host is prior or equal to 9.1.1, and is affected by multiple vulnerabilities. These vulnerabilities are contained within the Webkit subcomponent.

The version of iOS running on the mobile device is prior to 9.3.3. It is, therefore, affected by multiple vulnerabilities, the most serious of which can result in remote code execution, in the following components :

  - Calendar
  - CoreGraphics
  - FaceTime
  - ImageIO
  - IOAcceleratorFamily
  - IOHIDFamily
  - Kernel
  - libxml2
  - libxslt
  - Safari
  - Sandbox Profiles
  - Siri Contacts
  - Web Media
  - WebKit
  - WebKit JavaScript Bindings
  - WebKit Page Loading

The version of Apple Safari installed on the remote Mac OS X host is prior to 9.1.2. It is, therefore, affected by multiple vulnerabilities, the most serious of which can result in remote code execution, in the following components :

  - WebKit
  - WebKit JavaScript Bindings
  - WebKit Page Loading
