Multiple cryptographic issues in Python oic

Impact Client implementations using this library Issues 1 The IdToken signature algorithm was not checked automatically, but only if the expected algorithm was passed in as a kwarg. 2 JWA none algorithm was allowed in all flows. 3 oic.consumer.Consumer.parseauthz returns an unverified IdToken. Th...

Cipher Downgrade Attack

oic is vulnerable to cipher downgrade attacks. The vulnerability exists as the IdToken signature algorithm is not checked automatically, and that the JWA none algorithm is always allowed, and that the IdToken returned from oic.consumer.Consumer.parseauthz is not verified, and the iat claim is not...
