3. Description:

 

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.
