I think it should work.  Try this and let me know if the ZIP handler crashes...
* Open IIIIIIIIJJJJJJJJKKKKKKKKLLLLLLLL.zip
* Then the EEEEEEEEFFFFFFFFGGGGGGGGHHHHHHHH.zip embedded within
* Click the "UP-DIRECTORY" button
* Crash ...

It may be possible to exploit this without any user interaction, for
instance, while extraction is occurring.  Or, it may also be possible
to integrate a path similar to the '..' tar traversal that was
published recently.  I have no idea.  If you find that it does crash
on your latest updated XP, let us know...
