Django 1.4.8 release notes¶
September 14, 2013
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
The decoration of the
user_change_password user admin
did not include
since the views are methods) resulting in the decorator not being properly
applied. This usage has been fixed and
sensitive_post_parameters() will now
throw an exception if it’s improperly used.
