Comment 2 Tomas Hoger 2016-07-28 13:43:07 UTC 
This issue is triggered when iptcembed() function is called with long $iptcdata argument (not possible under default or typical PHP configurations that use much lower limit for memory that can be used by a script), or specified $jpeg_file_name must be a very large file.  Hence, this would be hard to trigger for remote attacker.
