prior versions

prior versions
Overview:
A vulnerabilitiy exists in Safari 2.0.3 (417.9.2) and perhaps in prior versions
which causes the operating system to slow down SRCOD (Spinning Rainbow Cursor
Of Death), and therefore, it's not possible to launch any applications like
Terminal to kill the process. After several minutes Safari crashes.
Technical Details:
Create a new File with following code ...
<HTML>
<TABLE>
<TR><TD ROWSPAN=2000000000>
.. then save it as a .html file (example.html) now open it in Safari. The
application takes a lot of CPU and RAM slowing down the operating system SRCOD
(Spinning Rainbow Cursor Of Death), and it is no longer possible to use OSX
even "apple" + "ALT" + "ESC" is working very slow!
Go around and pull the power cable out or press the startbutton for a while to
shut down the computer.
