Hello, Kamailio SIP Server v5.0.8 stable release is out. This is a maintenance release of the old stable branch 5.0, that includes fixes since the release of v5.0.7. There is no change to database schema or configuration language structure that you have to do on previous installations of v5.0.x. Deployments running previous v5.0.x versions are strongly recommended to be upgraded to v5.0.8 or even better directly to v5.1.x or v5.2.x because v5.0.x is getting out of the official maintenance time frame. Important note: this is the last planned release from branch5.0. For more details about version 5.0.8 (including links and guidelines to download the tarball or from GIT repository), visit: * https://www.kamailio.org/w/2019/04/kamailio-v5-0-8-released/ RPM, Debian/Ubuntu packages will be available soon as well. Note: the latest stable branch is 5.2, at this moment with its latest release v5.2.2. See more details about it at: * https://www.kamailio.org/w/kamailio-v5-2-0-release-notes/ Many thanks to all contributing and using Kamailio!

[kamailio/kamailio] dialog: segfault with db_mode = 1 and broken SIP message (#1899)

by Bastian Triller

### Description `dialog` module is configured with `db_mode` 1 (realtime). When receiving following broken SIP `200` response (missing 6 bytes between header and body), Kamailio crashes: ``` SIP/2.0 200 OK Via: SIP/2.0/UDP 1.2.3.4;branch=z9hG4bKa185.ad1e5804a90a4f79fa2b09b3b2118053.0 Via: SIP/2.0/UDP 2.3.4.5:7016;received=2.3.4.5;branch=z9hG4bK370933d4;rport=7016 Record-Route: <sip:1.2.3.4;lr=on;did=c41.dee> From: "1234" <sip:1234@example.com>;tag=as4cbf81fd To: <sip:2345@example.com>;tag=3450065082 Call-ID: 727ca44f1e962eb321143475380dfbd9(a)example.com CSeq: 102 INVITE Contact: <sip:2345@3.4.5.6:12500> Content-Type: application/sdp Allow: INVITE, INFO, PRACK, ACK, BYE, CANCEL, OPTIONS, NOTIFY, REGISTER, SUBSCRIBE, REFER, PUBLISH, UPDATE, MESSAGE Content-Length: 2170 o=- 20568 20568 IN IP4 3.4.5.6 s=SDP data c=IN IP4 3.4.5.6 t=0 0 m=audio 13002 RTP/AVP 8 101 a=rtpmap:8 PCMA/8000 a=ptime:20 a=rtpmap:101 telephone-event/8000 a=fmtp:101 0-15 a=sendrecv ``` Crash happens in [dlg_db_handler.c](https://github.com/kamailio/kamailio/blob/master/src/modu… ``` LM_DBG("sock_info is %.*s\n", cell->bind_addr[DLG_CALLER_LEG]->sock_str.len, cell->bind_addr[DLG_CALLEE_LEG]->sock_str.s); SET_STR_VALUE(values+7, cell->bind_addr[DLG_CALLER_LEG]->sock_str); SET_STR_VALUE(values+8, cell->bind_addr[DLG_CALLEE_LEG]->sock_str); ``` #### Debugging Data ``` Thread 1 (Thread 0x7fc64b620700 (LWP 2333)): +bt #0 0x00007fc641675b63 in update_dialog_dbinfo_unsafe (cell=0x7fc619a71ff8) at dlg_db_handler.c:784 #1 0x00007fc641676852 in update_dialog_dbinfo (cell=0x7fc619a71ff8) at dlg_db_handler.c:881 #2 0x00007fc64167c861 in dlg_onreply (t=0x7fc61d7888f0, type=1048576, param=0x7ffe1ce712f0) at dlg_handlers.c:509 #3 0x00007fc6443f4f17 in run_trans_callbacks_internal (cb_lst=0x7fc61d788960, type=1048576, trans=0x7fc61d7888f0, params=0x7ffe1ce712f0) at t_hooks.c:260 #4 0x00007fc6443f5144 in run_trans_callbacks_with_buf (type=1048576, rbuf=0x7fc61d7889b0, req=0x7fc61ec43928, repl=0x7fc646dcbd80, flags=0) at t_hooks.c:305 #5 0x00007fc6443aaabc in relay_reply (t=0x7fc61d7888f0, p_msg=0x7fc646dcbd80, branch=0, msg_status=200, cancel_data=0x7ffe1ce71580, do_put_on_wait=1) at t_reply.c:1950 #6 0x00007fc6443ae844 in reply_received (p_msg=0x7fc646dcbd80) at t_reply.c:2521 #7 0x000055fd54405df6 in do_forward_reply (msg=0x7fc646dcbd80, mode=0) at core/forward.c:749 #8 0x000055fd5440784b in forward_reply (msg=0x7fc646dcbd80) at core/forward.c:851 #9 0x000055fd544522d2 in receive_msg (buf=0x55fd5492d080 <buf> "SIP/2.0 200 OK\r\nVia: SIP/2.0/UDP ...", len=960, rcv_info=0x7ffe1ce71ad0) at core/receive.c:341 #10 0x000055fd5436e207 in udp_rcv_loop () at core/udp_server.c:515 #11 0x000055fd542dc608 in main_loop () at main.c:1623 #12 0x000055fd542e46a9 in main (argc=13, argv=0x7ffe1ce71f78) at main.c:2642 ``` ### Possible Solutions Check `bind_addr` before accessing. ### Additional Information Version was 5.0.x, but at least code in `dlg_handler.c` wasn't modified in `master` since then. -- You are receiving this because you are subscribed to this thread.
