WebKit, as used in Apple Safari before 4.1.3 and 5.0.x before 5.0.3, Google Chrome before 6.0.472.53, and webkitgtk before 1.2.6, does not properly restrict read access to images derived from CANVAS elements, which allows remote attackers to bypass the Same Origin Policy and obtain potentially sensitive image data via a crafted web site.

The remote host is affected by the vulnerability described in GLSA-201412-09 (Multiple packages, Multiple vulnerabilities fixed in 2011)

    Vulnerabilities have been discovered in the packages listed below.

From Red Hat Security Advisory 2011:0177 :

Updated webkitgtk packages that fix several security issues are now available for Red Hat Enterprise Linux 6.

The Red Hat Security Response Team has rated this update as having moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

WebKitGTK+ is the port of the portable web rendering engine WebKit to the GTK+ platform.

Multiple memory corruption flaws were found in WebKit. Malicious web content could cause an application using WebKitGTK+ to crash or, potentially, execute arbitrary code with the privileges of the user running the application. (CVE-2010-1782, CVE-2010-1783, CVE-2010-1784, CVE-2010-1785, CVE-2010-1787, CVE-2010-1788, CVE-2010-1790, CVE-2010-1792, CVE-2010-1807, CVE-2010-1814, CVE-2010-3114, CVE-2010-3116, CVE-2010-3119, CVE-2010-3255, CVE-2010-3812, CVE-2010-4198)

Multiple use-after-free flaws were found in WebKit. Malicious web content could cause an application using WebKitGTK+ to crash or, potentially, execute arbitrary code with the privileges of the user running the application. (CVE-2010-1780, CVE-2010-1786, CVE-2010-1793, CVE-2010-1812, CVE-2010-1815, CVE-2010-3113, CVE-2010-3257, CVE-2010-4197, CVE-2010-4204)

Two array index errors, leading to out-of-bounds memory reads, were found in WebKit. Malicious web content could cause an application using WebKitGTK+ to crash. (CVE-2010-4206, CVE-2010-4577)

A flaw in WebKit could allow malicious web content to trick a user into thinking they are visiting the site reported by the location bar, when the page is actually content controlled by an attacker.
(CVE-2010-3115)

It was found that WebKit did not correctly restrict read access to images created from the 'canvas' element. Malicious web content could allow a remote attacker to bypass the same-origin policy and potentially access sensitive image data. (CVE-2010-3259)

A flaw was found in the way WebKit handled DNS prefetching. Even when it was disabled, web content containing certain 'link' elements could cause WebKitGTK+ to perform DNS prefetching. (CVE-2010-3813)

Users of WebKitGTK+ should upgrade to these updated packages, which contain WebKitGTK+ version 1.2.6, and resolve these issues. All running applications that use WebKitGTK+ must be restarted for this update to take effect.

The remote mobile host is a using a version of Apple iOS earlier than 4.2. Such versions are potentially affected by multiple vulnerabilities. Apple iOS 4.2 contains security fixes for the following components :

  - Configuration Policies

  - CoreGraphics

  - FreeType

  - iAd Content Display

  - ImageIO

  - libxml

  - Mail

  - Networking

  - OfficeImport

  - Photos

  - Safari

  - Telephony

  - WebKit

  - Multiple components

The version of Safari installed on the remote Windows host is earlier than 5.0.3.  As such, it is potentially affected by numerous issues in its WebKit component that could allow arbitrary code execution, session tracking, address bar spoofing, and other sorts of attacks.

The version of Apple Safari installed on the remote Mac OS X host is earlier than 5.0.3 / 4.1.3.  As such, it is potentially affected by numerous issues in its WebKit component that could allow arbitrary code execution, session tracking, address bar spoofing, and other sorts of attacks.

Gustavo Noronha Silva reports :

The patches to fix the following CVEs are included with help from Vincent Danen and other members of the Red Hat security team:

A large number of security issues were discovered in the WebKit browser 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.

Please consult the bug listed at the top of this advisory to get the exact list of CVE numbers fixed for each release.
