Google Chrome的第一个Exploit

Posted by c4pr1c3 on September 3, 2008

早上第一时间下载并安装了Chrome,TNND,不知道是不是RPWT,打开任何的网页都是崩溃。。。

下午已经有人放出了第一个DoS Exploit,可见Google的强大影响力!

不废话了,下面是漏洞描述和PoC。

—————————————————

Software:

Google Chrome Browser 0.2.149.27

Tested:

Windows XP Professional SP3

Result:

Google Chrome Crashes with All Tabs

Problem:

An issue exists in how chrome behaves with undefined-handlers in chrome.dll version

0.2.149.27. A crash can result without user interaction. When a user is made to visit

a malicious link, which has an undefined handler followed by a ‘special’ character,

the chrome crashes with a Google Chrome message window “Whoa! Google Chrome has crashed.

Restart now?”. It lies in dealing with the POP EBP instruction when pointed out by the

EIP register at 0x01002FF4.
