Gagnon (egagnon) Assigned to: Nobody/Anonymous (nobody) Summary: Broken PGP/MIME signature of messages with attachments Initial Comment: Hi, When I send a PGP/MIME signed message *with* attachments (in addition to the PGP signature) to a Mailman-based mailing list, Firefox/Enigmail fails to verify the signature of the message forwarded by mailman. I have uploaded an example message with a broken signature as attachment to this bug. You can also see how Mailman's automatic archives don't even handle such messages correctly by looking at how it archived that message at: http://sablecc.org/lists/sablecc-user/2004-December/000159.html I've looked in the bugs database and found that a somewhat related problem was reported a while ago, but note that the current bug is different. The original bug was about PGP/MIME signed messages without attachments that were handled incorrectly by Enigmail. This one is about messages with attachments, and it is likely that the bug is Mailman's, at least accroding to the reply I got in: http://bugzilla.mozdev.org/show_bug.cgi?id=8466 Thanks for your help (and for the magnificient software)!

Message: Logged In: YES user_id=15365 Dear Bas, Thanks a lot for identifying the source of this bug and flagging an upstream bug on Python. Etienne ---------------------------------------------------------------------- Comment By: Bas Wijnen (shevek) Date: 2005-01-24 06:35 Message: Logged In: YES user_id=42389 I checked the source, and this appears to be a bug in Python. It can read and write e-mails, including headers, and they are interpreted. However, it doesn't preserve their whitespace, which is of course fatal for pgp signatures. The bug is filed for python here: http://sourceforge.net/tracker/index.php?func=detail&aid=968430&group_id=5470&atid=105470 ---------------------------------------------------------------------- Comment By: Etienne M. Gagnon (egagnon) Date: 2005-01-18 12:30 Message: Logged In: YES user_id=15365 I am attaching a screen shot of the content filtering settings (see the options.png attachment I have added to this bug report). In short, content filtering is disabled, so I don't think it is the cause of the problem. :-/ Etienne ---------------------------------------------------------------------- Comment By: Brad Knowles (shub) Date: 2005-01-16 19:37 Message: Logged In: YES user_id=18417 Look at your content filter settings. What MIME-types are you configured to pass? At the very least, you should be configured to pass the following: multipart/mixed multipart/alternative text/plain application/pgp-signature multipart/signed ---------------------------------------------------------------------- Comment By: Toni Willberg (toniw) Date: 2005-01-07 20:23 Message: Logged In: YES user_id=190645 I can reproduce this bug also. Here's a diff what happened to me: diff -u mail.valid mail.invalid Content-Disposition: attachment; filename=configure.in.pre-pkgconfig.patch -Content-Type: text/x-patch; name=configure.in.pre-pkgconfig.patch; charset=UTF-8 +Content-Type: text/x-patch; name=configure.in.pre-pkgconfig.patch; + charset=UTF-8 Content-Transfer-Encoding: base64 And this was _inside_ gpg-signed block. Mailman should not alter that section at all, right? X-Mailman-Version: 2.1.4 Yours, Toni Willberg <toniw@iki.fi> ---------------------------------------------------------------------- Comment By: Etienne M.
