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.
