Description Kurt Seifried 2013-02-20 09:26:20 UTC 
James Bennett of Django reports:

Django's serialization framework includes support for serializing to, and deserializing from, XML. Django's XML deserialization is vulnerable to entity-expansion and external-entity/DTD attacks.

To remedy this, Django's XML deserializer no longer allows DTDs, performs entity expansion, or fetches external entities/DTDs. Note that this only protects Django's XML serialization framework; if your application parses XML, we recommend you look into the defusedxml Python packages which remedy this for Python itself.

Because this issue also affects Python's XML libraries, it is covered by Python's CVE-2013-1664 and CVE-2013-1665.
