Descriptions

util/emailutils.py in Matrix Sydent before 1.0.2 mishandles registration restrictions that are based on e-mail domain, if the allowed_local_3pids option is enabled. This occurs because of potentially unwanted behavior in Python, in which an email.utils.parseaddr call on user@bad.example.net@good.example.com returns the user@bad.example.net substring.

Esto ocurre debido a un comportamiento potencialmente no deseado en Python, en el que una llamada de email.utils.parseaddr en user@bad.example.net@good.example.com devuelve la subcadena user@bad.example.net.
