# Django 1.11.19 release notes

*February 11, 2019*

Django 1.11.19 fixes a security issue in 1.11.18.

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

If `django.utils.numberformat.format()` – used by `contrib.admin` as well
as the 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.
