USN-1632-1 fixed a vulnerability in Django. The upstream fix introduced
testsuite failures when ADMINS and/or MANAGERS were defined in settings.py.
This update fixes the problem.
We apologize for the inconvenience.
Original advisory details:
James Kettle discovered Django did not properly filter the Host HTTP header
when processing certain requests. An attacker could exploit this to
generate and display arbitrary URLs to users.
