Log Message:
Changes 1.4.5:
Security-fix release. Here's a brief summary of each issue and its resolution:

Issue: Host header poisoning: an attacker could cause Django to generate and 
display URLs that link to arbitrary domains. This could be used as part of a 
phishing attack. These releases fix this problem by introducing a new setting, 
ALLOWED_HOSTS, which specifies a whitelist of domains your site is known to 
respond to.

Important: by default Django 1.3.6 and 1.4.4 set ALLOWED_HOSTS to allow all 
hosts. This means that to actually fix the security vulnerability you should 
define this setting yourself immediately after upgrading.

Issue: Formset denial-of-service: an attacker can abuse Django's tracking of 
the number of forms in a formset to cause a denial-of-service attack. This has 
been fixed by adding a default maximum number of forms of 1,000. You can still 
manually specify a bigger max_num, if you wish, but 1,000 should be enough for 

Issue: XML attacks: Django's serialization framework was vulnerable to attacks 
via XML entity expansion and external references; this is now fixed. However, 
if you're parsing arbitrary XML in other parts of your application, we 
recommend you look into the defusedxml Python packages which remedy this 
anywhere you parse XML, not just via Django's serialization framework.

Issue: Data leakage via admin history log: Django's admin interface could 
expose supposedly-hidden information via its history log. This has been fixed.
