Apple QuickTime 7.5.5 / iTunes 8.0 - Remote Off-by-One Crash

###############################################################################
# Quicktime7.5.5/Itunes 8.0 Remote Heap Overflow Crash
# Vendor: http://www.apple.com/
# Risk : high
#
# The "<? quicktime type= ?>" tag fail to handle long strings, which can lead to a heap overflow in Quicktime/Itunes media player.
# This bug can be remote or local, Quicktime/Itunes parse any supplied file for  a reconized header even if the header is not  corresponding
# to the filetype, so you can put some xml in a mp4, mov,etc and open it with quicktime or you can do the same in some html page leading to a
# remote crash on firefox, IE and any browser using the Quicktime plugin.
# Code execution may be possible.
