James Davis discovered two issues in Django, a high-level Python web development framework, that can lead to a denial-of-service attack. An attacker with control on the input of the django.utils.html.urlize() function or django.utils.text.Truncator’s chars() and words() methods could craft a string that might stuck the execution of the application.
