Django 1.4.2 release notes
|
|
==========================
|
|
|
|
*October 17, 2012*
|
|
|
|
This is the second security release in the Django 1.4 series.
|
|
|
|
Host header poisoning
|
|
---------------------
|
|
|
|
Some parts of Django -- independent of end-user-written applications -- make
|
|
use of full URLs, including domain name, which are generated from the HTTP Host
|
|
header. Some attacks against this are beyond Django's ability to control, and
|
|
require the web server to be properly configured; Django's documentation has
|
|
for some time contained notes advising users on such configuration.
|
|
|
|
Django's own built-in parsing of the Host header is, however, still vulnerable,
|
|
as was reported to us recently. The Host header parsing in Django 1.3.3 and
|
|
Django 1.4.1 -- specifically, django.http.HttpRequest.get_host() -- was
|
|
incorrectly handling username/password information in the header. Thus, for
|
|
example, the following Host header would be accepted by Django when running on
|
|
"validsite.com"::
|
|
|
|
Host: validsite.com:random@evilsite.com
|
|
|
|
Using this, an attacker can cause parts of Django -- particularly the
|
|
password-reset mechanism -- to generate and display arbitrary URLs to users.
|
|
|
|
To remedy this, the parsing in HttpRequest.get_host() is being modified; Host
|
|
headers which contain potentially dangerous content (such as username/password
|
|
pairs) now raise the exception django.core.exceptions.SuspiciousOperation
|
|
|
|
Details of this issue were initially posted online as a `security advisory`_.

Backwards incompatible changes
|
|
==============================
|
|
|
|
* The newly introduced :class:`~django.db.models.GenericIPAddressField`
|
|
constructor arguments have been adapted to match those of all other model
|
|
fields. The first two keyword arguments are now verbose_name and name.
|
|
|
|
