Product Background

Problem Background
===================

Konqueror crashes if JavaScript code tries to read the source of a
child iframe which is set to an FTP URL.

Impact
======

It is possible for malicious websites to crash Konqueror and possibly
other applications with rely on KJS.

The KDE JavaScript implementation, KJS has been found to crash when it
tries to read the contents of an FTP iframe. This can be demonstrated
by creating a web page with an iframe with a src of
"ftp://localhost/anything", then reading the contents of this iframe
with JavaScript similar to the following. (A working FTP server is not
required).
document.getElementById(iframe_name).contentWindow.document.body.innerHTML;

I can reproduce this crash with Konqueror in kde-base-3.5.6-3, using
this exploit:
http://bindshell.net/advisories/konq355/konq355-crash-demo.zip
but I can't test if the patch works because I'm testing makepkg3, that
have bugs which block compiling.
Please, post your feedback on this.
