Django 1.4.8 release notes
|
|||
|
|
==========================

Django 1.4.8 fixes two security issues present in previous Django releases in
|
|||
|
|
the 1.4 series.
|
|||
|
|
|
|||
|
|
Denial-of-service via password hashers
|
|||
|
|
--------------------------------------
|
|||
|
|
|
|||
|
|
In previous versions of Django, no limit was imposed on the plaintext
|
|||
|
|
length of a password. This allowed a denial-of-service attack through
|
|||
|
|
submission of bogus but extremely large passwords, tying up server
|
|||
|
|
resources performing the (expensive, and increasingly expensive with
|
|||
|
|
the length of the password) calculation of the corresponding hash.
|
|||
|
|
|
|||
|
|
As of 1.4.8, Django's authentication framework imposes a 4096-byte
|
|||
|
|
limit on passwords and will fail authentication with any submitted
|
|||
|
|
password of greater length.
|
|||
|
|
|
|||
|
|
Corrected usage of :func:`~django.views.decorators.debug.sensitive_post_parameters` in :mod:`django.contrib.auth`’s admin
|
|||
|
|
-------------------------------------------------------------------------------------------------------------------------
|
|||
|
|
|
|||
|
|
The decoration of the ``add_view`` and ``user_change_password`` user admin
|
|||
|
|
views with :func:`~django.views.decorators.debug.sensitive_post_parameters`
|
|||
|
|
did not include :func:`~django.utils.decorators.method_decorator` (required
|
|||
|
|
since the views are methods) resulting in the decorator not being properly
|
|||
|
|
applied. This usage has been fixed and
|
|||
|
|
:func:`~django.views.decorators.debug.sensitive_post_parameters` will now
|
|||
|
|
throw an exception if it's improperly used.
