# Django 4.2.18 release notes

*January 14, 2025*

Django 4.2.18 fixes a security issue with severity «moderate» in 4.2.17.

## CVE-2024-56374: Potential denial-of-service vulnerability in IPv6 validation

Lack of upper bound limit enforcement in strings passed when performing IPv6
validation could lead to a potential denial-of-service attack. The undocumented
and private functions `clean_ipv6_address` and `is_valid_ipv6_address` were
vulnerable, as was the  [`django.forms.GenericIPAddressField`](/el/4.2/ref/forms/fields/#django.forms.GenericIPAddressField) form field,
which has now been updated to define a `max_length` of 39 characters.

The [`django.db.models.GenericIPAddressField`](/el/4.2/ref/models/fields/#django.db.models.GenericIPAddressField) model field was not
affected.
