Apple Mac OS X Safari 2.0.3 Vulnerability
=========================================

Release Date:
April 23th, 2006

Vendor:
Apple Computer Inc.

Tested on:
iBook G4 1.2 GHz with Mac OS X 10.4.5 (Build 8H14) + all Updates from Apple
except "10.4.6 Update"
iBook G4 1.33 GHz with Mac OS X 10.4.6 (Build 8I127) + all Updates from
Apple
PowerMac G4 Dual 867 MHz with Mac OS X 10.4.6 (Build 8I127) + all Updates
from Apple
iMac G4 800 MHz with Mac OS X 10.4.6 (Build 8I127) + all Updates from Apple

Versions affected:
Safari 2.0.3 (417.9.2) latest version under 10.4.5 (Build 8H14) and 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.

For an expample klick at the link with Safari (WARNING: That crashes Safari
after several minutes an first the SRCOD (Spinning Rainbow Cursor Of Death)
is there for all the time!)
