Original advisory details:

 Jedediah Smith discovered that Django incorrectly handled underscores in
 WSGI headers. A remote attacker could possibly use this issue to spoof
 headers in certain environments. (CVE-2015-0219)

 Mikko Ohtamaa discovered that Django incorrectly handled user-supplied
 redirect URLs. A remote attacker could possibly use this issue to perform a
 cross-site scripting attack. (CVE-2015-0220)

 Alex Gaynor discovered that Django incorrectly handled reading files in
 django.views.static.serve(). A remote attacker could possibly use this
 issue to cause Django to consume resources, resulting in a denial of
 service. (CVE-2015-0221)

 Keryn Knight discovered that Django incorrectly handled forms with
 ModelMultipleChoiceField. A remote attacker could possibly use this issue
 to cause a large number of SQL queries, resulting in a database denial of
 service. This issue only affected Ubuntu 14.04 LTS and Ubuntu 14.10.
