[Bug 1462755] [NEW] qrunner crashes on invalid unicode sequence
by Thijs Kinkhorst 28 Feb '22

28 Feb '22

Public bug reported: When a message contains an invalud unicode sequence in its header, qrunner flat out crashes on that: May 17 15:32:20 2015 (981) Uncaught runner exception: 'utf8' codec can't decode byte 0xe9 in position 18: invalid continuation byte May 17 15:32:20 2015 (981) Traceback (most recent call last): File "/var/lib/mailman/Mailman/Queue/Runner.py", line 119, in _oneloop self._onefile(msg, msgdata) File "/var/lib/mailman/Mailman/Queue/Runner.py", line 190, in _onefile keepqueued = self._dispose(mlist, msg, msgdata) File "/var/lib/mailman/Mailman/Queue/IncomingRunner.py", line 130, in _dispose more = self._dopipeline(mlist, msg, msgdata, pipeline) File "/var/lib/mailman/Mailman/Queue/IncomingRunner.py", line 153, in _dopipeline sys.modules[modname].process(mlist, msg, msgdata) File "/var/lib/mailman/Mailman/Handlers/CookHeaders.py", line 239, in process i18ndesc = uheader(mlist, mlist.description, 'List-Id', maxlinelen=998) File "/var/lib/mailman/Mailman/Handlers/CookHeaders.py", line 65, in uheader return Header(s, charset, maxlinelen, header_name, continuation_ws) File "/usr/lib/python2.7/email/header.py", line 183, in __init__ self.append(s, charset, errors) File "/usr/lib/python2.7/email/header.py", line 267, in append ustr = unicode(s, incodec, errors) UnicodeDecodeError: 'utf8' codec can't decode byte 0xe9 in position 18: invalid continuation byte May 17 15:32:20 2015 (981) SHUNTING: 1431869540.389822+156779307d54473d0eb732994bb67eee95733285 A solution for this specific case is to have Mailman/Handlers/CookHeaders.py pass the erorrs='replace' parameter. I would say that this is actually a bug in python-email, since I think it doesn't make sense to set errors to "strict" rather than something like "replace" when the intention is to parse stuff so free-formed, under-specd and user-controlled as email. Nonetheless, Mailman already sets errors='replace' in some places so it might aswell add it here. ** Affects: mailman Importance: Undecided Status: New -- You received this bug notification because you are a member of Mailman Coders, which is subscribed to GNU Mailman. https://bugs.launchpad.net/bugs/1462755 Title: qrunner crashes on invalid unicode sequence To manage notifications about this bug go to: https://bugs.launchpad.net/mailman/+bug/1462755/+subscriptions
