Description

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.

Solution

Update the affected packages.
