and DTD-retrieval issues.

functionality for building a SAML2 service provider or an identity
provider, to be used in a WSGI environment.

Security Fix(es):

* An XML entity expansion vulnerability was found in python-pysaml2. A
remote attacker could send a crafted request which would cause denial of
service through resource exhaustion. (CVE-2016-10149)
