perhaps prior versions
Safari 2.0.3 (417.9.2) latest version under 10.4.6 (Build 8I127)
and perhaps 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.

Rainbow Cursor Of Death) is there for all the time!) http://
