New submission from Nikita Hoffmann :
Parsing an invalid email message id can throw a header parser error. A bug in
parse_message_ still tries to append the unset token to a variable.
File "/opt/python-3.8.0/lib/python3.8/email/_header_value_parser.py", line
2116, in parse_message_
id
message_id.append(token)
UnboundLocalError: local variable 'token' referenced before assignment
Version 3.7 is not affected.
