Django 1.5.5 release notes
|
|
==========================
|
|
|
|
*October 23, 2013*
|
|
|
|
Django 1.5.5 fixes a couple security-related bugs and several other bugs in the
|
|
1.5 series.
|
|
|
|
Readdressed denial-of-service via password hashers
|
|
--------------------------------------------------
|
|
|
|
Django 1.5.4 imposes a 4096-byte limit on passwords in order to mitigate a
|
|
denial-of-service attack through submission of bogus but extremely large
|
|
passwords. In Django 1.5.5, we've reverted this change and instead improved
|
|
the speed of our PBKDF2 algorithm by not rehashing the key on every iteration.
|
|
|
|
Properly rotate CSRF token on login
|
|
-----------------------------------
|
|
|
|
This behavior introduced as a security hardening measure in Django 1.5.2 did
|
|
not work properly and is now fixed.
|
|
|
|
