Hi,
we get core dumps of imapd on commands like this:
A7 APPEND "INBOX/Junk E-mail" () "29-Jul-2016 07:17:38 +0000" CATENATE
(URL "/INBOX/;uid=44335/;section=TEXT.MIME" URL
"/INBOX/;uid=44335/;section=TEXT")
Connection closed by foreign host.
Tested with:
Cyrus 2.4.18 on Solaris 11
Cyrus 2.4.17 on CentOS 7
section=MIME instead of section=TEXT.MIME (which I think is not a valid
section) works for the message:
A7 APPEND "INBOX/Junk E-mail" () "29-Jul-2016 07:17:38 +0000" CATENATE
(URL "/INBOX/;uid=44335/;section=MIME" URL
"/INBOX/;uid=44335/;section=TEXT")
A7 OK [APPENDUID 1469792687 169] Completed
To illustrate the issue we produced core dumps with some nonsense
sections, example:
A7 APPEND "INBOX/Junk E-mail" () "29-Jul-2016 07:17:38 +0000" CATENATE
(URL "/INBOX/;uid=44335/;section=CATS_AND_DOGS" URL
"/INBOX/;uid=44335/;section=TEXT")
Connection closed by foreign host.
This is the stacktrace of the corresponding core file (produced with
Cyrus 2.4.17):

I don’t know where to fix it best in order to get BADURL or something
instead of a core dump, so any help would be highly appreciated.

Edda
