dovecot - May 2015 - v2.2.17 Segfault

Hi,

I'm using libexec/dovecot/imap via a ssh tunnel. 2.2.17 segfaults while
accessing a NULL pointer. The following change fixes it for me:


--- dovecot-2.2.17/src/lib-imap/imap-keepalive.c	2015-05-03 11:12:11.000000000
+0200
+++ dovecot-2.2.17/src/lib-imap/imap-keepalive.c	2015-05-14 20:06:29.490617405
+0200
@@ -11,6 +11,8 @@
 {
 	unsigned int addr;
 
+	if (!ip)
+		return FALSE;
 	if (ip->family == 0)
 		return FALSE;
 	if (ip->family == AF_INET) {



Thanks,
Adam

Slightly different fix: http://hg.dovecot.org/dovecot-2.2/rev/4c4eff229426
