Summary: IMAPD crashes when exposed to internet
Description:
Hi there
This is my first post here, I have just registered, so excuse me if i am
doing it all wrong.
dbmail-imapd crashes whenever i allow users to login (probably a certain
user triggering the segfault with a certain command), if i block public
access and use IMAP through web mail or any other, it works fine, seconds
after allowing traffic to the deamon, it will crash
I have compiled the debug binaries, then run dbmail-imapd from within gdb,
right after the crash, i issue a bt, and here are the commands and results
root@email:/usr/local/sbin# gdb /usr/sbin/dbmail-imapd -p
/run/dbmail/dbmail-imapd.pid
