WebKit in Apple Safari before 6.2.1, 7.x before 7.1.1, and 8.x before 8.0.1 allows remote attackers to bypass the Same Origin Policy via crafted Cascading Style Sheets (CSS) token sequences within an SVG file in the SRC attribute of an IMG element.

According to its banner, the remote Safari browser is missing a security update to Webkit.  Safari is bundled with Apple WebKit.  Apple WebKit is affected by the following vulnerabilities :

 - There is a 'use-after-free' vulnerability which can allow remote attackers to execute arbitrary code through crafted page objects within HTML. (CVE-2014-4459)
 - There is a policy bypass flaw which can allow remote attackers to bypass the 'Same Origin Policy' via Cascading Style Sheets. (CVE-2014-4465)

According to its banner, the remote Apple TV device is a version prior to 7.0.3. It is, therefore, affected by the following vulnerabilities :

  - Multiple memory corruption issues exist, related to the     included version of WebKit, that allow application     crashes or arbitrary code execution. (CVE-2014-3192,     CVE-2014-4459, CVE-2014-4466, CVE-2014-4468,     CVE-2014-4469, CVE-2014-4470, CVE-2014-4471,     CVE-2014-4472, CVE-2014-4473, CVE-2014-4474,     CVE-2014-4475, CVE-2014-4476, CVE-2014-4477,     CVE-2014-4479)

  - A state management issue exists due to improperly     handling overlapping segments in Mach-O executable     files. A local user can exploit this issue to execute     unsigned code. (CVE-2014-4455)

  - A security bypass issue exists due to improper     validation of SVG files loaded in an IMG element. An     attacker can load a CSS of cross-origin resulting in     information disclosure. (CVE-2014-4465)

  - An issue exists due to the symbolic linking performed     by the 'afc' command which allows an attacker to     access arbitrary files on the system. (CVE-2014-4480)

  - An integer overflow issue exists due to improper bounds     checking when processing PDF files. (CVE-2014-4481)

  - A buffer overflow issue exists due to improper bounds     checking when processing fonts in PDF files.
    (CVE-2014-4483)

  - A memory corruption issue exists due to improper bounds     checking when processing '.dfont' files.
    (CVE-2014-4484)

  - A buffer overflow issue exists due to improper bounds     checking when processing XML files. (CVE-2014-4485)

  - A null pointer dereference issue exists due to the     handling of resource lists in the IOAcceleratorFamily     kernel extension. (CVE-2014-4486)

  - A buffer overflow issue exists due to improper size     validation in the IOHIDFamily. (CVE-2014-4487)

  - A validation issue exists due to the handling of     resource queue metadata in the IOHIDFamily kernel     extension. (CVE-2014-4488)

  - A null pointer dereference issue exists due to the     handling of event queues in the IOHIDFamily kernel     extension. (CVE-2014-4489)

  - An information disclosure issue exists due to the     handling of APIs related to kernel extensions in which     kernel addresses may be revealed. An attacker can     leverage this to bypass ASLR protections.
    (CVE-2014-4491)

  - Multiple type confusion issues exists due to improper     type checking during interprocess communication in the     network daemon (networkd). (CVE-2014-4492)

  - An issue exists due to improper checking of shared     memory permissions in the kernel shared memory     subsystem. (CVE-2014-4495)

  - An information disclosure issue exists due to     mach_port_kobject kernel interface leaking kernel     addresses and heap permutation values. An attacker can     leverage this to bypass ASLR protections.
    (CVE-2014-4496)

Note that arbitrary code execution is possible with the above issues assigned CVE-2014-4481 through CVE-2014-4489, CVE-2014-4492, and CVE-2014-4495.

The mobile device is running a version of iOS prior to version 8.1.3.
It is, therefore, affected by vulnerabilities in the following components :

  - AppleFileConduit
  - CoreGraphics
  - dyld
  - FontParser
  - Foundation
  - IOAcceleratorFamily
  - IOHIDFamily
  - iTunes Store
  - Kernel
  - libnetcore
  - MobileInstallation
  - Springboard
  - WebKit

The version of Safari installed on the remote Mac OS X host is a version prior to 6.2.2 / 7.1.2 / 8.0.2. It is, therefore, affected by the following vulnerabilities in WebKit :

 - A UI spoofing flaw exists in the handling of scrollbar boundaries. Visiting websites that frame malicious content can allow the UI to be spoofed. (CVE-2014-1748)
 - An SVG loaded in an IMG element could load a CSS file cross-origin. This can allow data exfiltration. (CVE-2014-4465)

  - Multiple memory corruption errors exist in WebKit that could potentially be leveraged for arbitrary code execution. (CVE-2014-4452, CVE-2014-4459, CVE-2014-4466, CVE-2014-4468, CVE-2014-4469, CVE-2014-4470, CVE-2014-4471, CVE-2014-4472, CVE-2014-4473, CVE-2014-4474, CVE-2014-4475)

Note that the 6.2.2 / 7.1.2 / 8.0.2 Safari updates include the security content of the 6.2.1 / 7.1.1 / 8.0.1 updates. These more recent updates, however, were released to fix potential issues with the installation of the previous patch release.
