The XSS auditor in WebKit, as used in Apple iOS before 9.3 and Safari before 9.1, does not properly handle redirects in block mode, which allows remote attackers to obtain sensitive information via a crafted URL.

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

  - The XSS auditor in WebKit, as used in Apple iOS before 9.3 and Safari before 9.1, does not properly handle     redirects in block mode, which allows remote attackers to obtain sensitive information via a crafted URL.
    (CVE-2016-1864)

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

The version of Safari installed on the remote host is prior or equal to 9.0.3, and is affected by multiple vulnerabilities in the following components :

 - Libxml2 (2016-1762)
 - Safari (CVE-2009-2197)
 - Safari Downloads (CVE-2016-1771)
 - Safari Top Sites (CVE-2016-1772)
 - WebKit (CVE-2016-1778, CVE-2016-1779, CVE-2016-1781, CVE-2016-1782, CVE-2016-1783, CVE-2016-1784, CVE-2016-1785, CVE-2016-1786, CVE-2016-1864)
 - WebKit History (CVE-2016-1784)
 - WebKit Page Loading (CVE-2016-1785, CVE-2016-1786)

The remote host is running a version of Mac OS X that is 10.11.x prior to 10.11.6. It is, therefore, affected by multiple vulnerabilities in the following components :

  - apache_mod_php
  - Audio
  - bsdiff
  - CFNetwork
  - CoreGraphics
  - FaceTime
  - Graphics Drivers
  - ImageIO
  - Intel Graphics Driver
  - IOHIDFamily
  - IOKit
  - IOSurface
  - Kernel
  - libc++abi
  - libexpat
  - LibreSSL
  - libxml2
  - libxslt
  - Login Window
  - OpenSSL
  - QuickTime
  - Safari Login AutoFill
  - Sandbox Profiles

Note that successful exploitation of the most serious issues can result in arbitrary code execution.

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
