…aders (pythonGH-14794) * bpo-37461: Fix infinite loop in parsing of specially crafted email headers. Some crafted email header would cause the get_parameter method to run in an infinite loop causing a DoS attack surface when parsing those headers. This patch fixes that by making sure the DQUOTE character is handled to prevent going into an infinite loop.
