aliases:
- CVE-2024-56374
- GHSA-qcgg-j2x8-h9g8
details: An issue was discovered in Django 5.1 before 5.1.5, 5.0 before 5.0.11, and
  4.2 before 4.2.18. 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
  are vulnerable, as is the django.forms.GenericIPAddressField form field. (The django.db.models.GenericIPAddressField
  model field is not affected.)
