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 Updat
e"
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 oper
ating 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 e
ven "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

Cursor Of Death) is there for all the time!) http://www.yanux.ch/exploits/safari/example.html
