Gekco Browsers DoS
------------------------------------------------------------------------
SUMMARY
A denial of service vulnerability in the Gekco based browsers (Mozilla
suite, Firefox and Camino) allows attackers to crash the browser by
crafting a special Javascript code.
DETAILS
Vulnerable Systems:
* Mozilla Suite version 1.7.8
* Firefox version 1.0.4
* Camino version 0.8.4
By using a specially crafted JavaScript function, it is possible to crash
the above named browsers. The script can be executed both with and without
user intervention.
Proof of Concept:
for (a = 0; a <= 20000; a++)
{
//Here is the special code that terminates the browser
function(){};
}
//Displays an alert to notify the user if the browser is not vulnerable.
alert("Good news - Your browser is not vulnerable.");
Workaround:
Disable Javascript for untrusted web sites.
