Subject: [PATCH 6/7] Fix CVE-2021-21239 - Restrict the key data that xmlsec1
 accepts to only x509 certs

All users of pysaml2 that use the default CryptoBackendXmlSec1 backend and need to
verify signed SAML documents are impacted. pysaml2 <= 6.4.1 does not ensure that a
signed SAML document is correctly signed. The default CryptoBackendXmlSec1 backend is
using the xmlsec1 binary to verify the signature of signed SAML documents, but by
default, xmlsec1 accepts any type of key found within the given document. xmlsec1 needs
to be configured explicitly to only use only x509 certificates for the verification
process of the SAML document signature.
