Django 1.11.19 修复了 1.11.18 中的一个安全问题。

## CVE-2019-6975: Memory exhaustion in `django.utils.numberformat.format()`

If `django.utils.numberformat.format()` -- used by `contrib.admin` as well as the `floatformat`, `filesizeformat`, and `intcomma` templates filters -- received a `Decimal` with a large number of digits or a large exponent, it could lead to significant memory usage due to a call to `'{:f}'.format()`.

To avoid this, decimals with more than 200 digits are now formatted using scientific notation.
