CVE-2015-0221

La visualización django.views.static.serve en Django anterior a 1.4.18, 1.6.x anterior a 1.6.10, y 1.7.x anterior a 1.7.3 lee ficheros por líneas enteras, lo que permite a atacantes remotos causar una denegación de servicio (consumo de memoria) a través de una línea larga en un fichero.

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. 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. 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. 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. Note that this issue only affected python-django. Cross-site scripting vulnerability in the contents function in admin/helpers.py in Django before 1.7.6 and 1.8 before 1.8b2 allows remote attackers to inject arbitrary web script or HTML via a model attribute in ModelAdmin.readonly_fields, as demonstrated by a \@property.
