From 0400d33928e6b463db164836da670700f03edc5d Mon Sep 17 00:00:00 2001 From: R David Murray Date: Sat, 8 Feb 2014 13:12:00 -0500 Subject: #16983: Apply postel's law to encoded words inside quoted strings. This applies only to the new parser. The old parser decodes encoded words inside quoted strings already, although it gets the whitespace wrong when it does so. This version of the patch only handles the most common case (a single encoded word surrounded by quotes), but I haven't seen any other variations of this in the wild yet, so its good enough for now. --- Lib/email/_header_value_parser.py | 7 +++++++ 1 file changed, 7 insertions(+) (limited to 'Lib/email/_header_value_parser.py') diff --git a/Lib/email/_header_value_parser.py b/Lib/email/_header_value_parser.py index 291437c5867..0369e015477 100644 --- a/Lib/email/_header_value_parser.py +++ b/Lib/email/_header_value_parser.py @@ -1559,6 +1559,13 @@ def get_bare_quoted_string(value): while value and value[0] != '"': if value[0] in WSP: token, value = get_fws(value) + elif value[:2] == '=?': + try: + token, value = get_encoded_word(value) + bare_quoted_string.defects.append(errors.InvalidHeaderDefect( + "encoded word inside quoted string")) + except errors.HeaderParseError: + token, value = get_qcontent(value) else: token, value = get_qcontent(value) bare_quoted_string.append(token) -- cgit v1.2.3
