Summary: dovecot authenticator segmentation fault in -bh mode
Product: Exim
Version: Any
Platform: Other
OS/Version: All
Status: NEW
Severity: bug
Priority: medium
Component: SMTP Authentication
AssignedTo: ph10@???
ReportedBy: nigel@???
QAContact: exim-dev@???
Reported by w@???
I've discovered a non-critical, yet annoying bug in dovecot
authenticator code. When I launch exim in the -bh (fake SMTP session)
mode and launch an AUTH command with dovecot authenticator configured
with it, exim goes SIGSEGV:
AUTH PLAIN whatever
SMTP<< AUTH PLAIN whatever
dovecot authentication
received: MECH PLAIN plaintext
received: MECH LOGIN plaintext
received: VERSION 1 0
received: SPID 74453
received: CUID 6
received: DONE
zsh: segmentation fault (core dumped) exim -bh 1.1.1.1 -d
After a bit of debugging I've found that deliver.c uses the
interface_address variable to determine if the connection is secured,
however in the -bh mode the variable is NULL. Thus, this simple patch
(attached) fixes the thing.
