[poppler] [PATCH] Avoid DoS due to huge number of JPX tiles in a stream

[Even Rouault]

Hi, 

The attached patch (against poppler 0.21.4) fixes a DoS due to huge number of 
JPX tiles in a stream. Also attached the PDF to reproduce the bug.
 
Note: a similar fix was committed in OpenJPEG recently: 
http://code.google.com/p/openjpeg/source/detail?r=2239

Best regards,

Even
