Details

The password reset functionality in django.contrib.auth in Django before 1.1.3, 1.2.x before 1.2.4, and 1.3.x before 1.3 beta 1 does not validate the length of a string representing a base36 timestamp, which allows remote attackers to cause a denial of service (resource consumption) via a URL that specifies a large base36 integer.
