The culprit seems to be session.c line 1019 or so: snprintf(buf, sizeof buf, "%.50s %d %.50s %d", get_remote_ipaddr(), get_remote_port(), get_local_ipaddr(packet_get_connection_in()), get_local_port()); After poking around, it seems that: 1) get_local_ipaddr returns NULL 2) this NULL is passed to snprintf 3) which dereferences the NULL causing a SEGV (get_local_ipaddr returns NULL because it calls get_socket_address which calls getpeername on a non...

I've looked at the sourcecode and maybe the following could do something I described : session.c:871 RCSID("$OpenBSD: session.c,v 1.142 2002/06/26 13:49:26 deraadt Exp $"); do_setup_env child_set_env(&env, &envsize, "SSH_LOCAL_IP", get_local_ipaddr(packet_get_connection_in()); what do you think of it ? thanx, mario

...pplied to OpenSSH 6.2p2 which fixes this problem. I would appreciate it if you would consider including it in a future release. One minor ugliness here is that I had to use "get_sock_port()" instead of get_local_port(), as get_local_port() doesn't take a socket as an argument the way get_local_ipaddr() does and there's no equivalent function under another name. Cleaning this up would impact other files, though, and I wanted to keep the diff as clean as possible. -- You are receiving this mail because: You are watching the assignee of the bug.
