Description

A weakness has been reported in Django, which can be exploited by malicious people to disclose 
certain sensitive information.

The weakness is caused due to the "authenticate()" function returning responses at different times 
depending on validity of the provided user name. This can be exploited to enumerate valid user 
names.

The weakness is reported in version 1.5. Other versions may also be affected.


Solution:
Fixed in the GIT repository.
