Descriptions

An issue was discovered in Django 1.11.x before 1.11.23, 2.1.x before 2.1.11, and 2.2.x before 2.2.4. Due to the behaviour of the underlying HTMLParser, django.utils.html.strip_tags would be extremely slow to evaluate certain inputs containing large sequences of nested incomplete HTML entities.

Se detectó un problema en Django versiones 1.11.x anteriores a 1.11.23, versiones 2.1.x anteriores a 2.1.11 y versiones 2.2.x anteriores a 2.2.4. Debido al comportamiento del HTMLParser subyacente, django.utils.html.strip_tags sería extremadamente lento para evaluar ciertas entradas que contienen secuencias largas de entidades HTML incompletas anidadas.
