  9. CVE-2019-6975: Memory exhaustion in ``django.utils.numberformat.format()``
    
  10. --------------------------------------------------------------------------
    
  11. 
    
  12. If ``django.utils.numberformat.format()`` -- used by ``contrib.admin`` as well
    
  13. as the ``floatformat``, ``filesizeformat``, and ``intcomma`` templates filters
    
  14. -- received a ``Decimal`` with a large number of digits or a large exponent, it
    
  15. could lead to significant memory usage due to a call to ``'{:f}'.format()``.
    
  16. 
    
  17. To avoid this, decimals with more than 200 digits are now formatted using
    
  18. scientific notation.
