FS#435 - crash in parser/sdp/sdp_helpr_funcs.c
User who did this - Michael Ricordeau (mricordeau)

----------
I tried to reproduce the same INVITE with wrong codec and with same kamailio version and I'm getting an error, no crash :
ERROR: <core> [parser/sdp/sdp_helpr_funcs.c:246]: extract_rtpmap(): invalid encoding in `a=rtpmap'

I have attached the python script (basic socket ...) used to send the SIP INVITE from gdb trace .

The function is called here in kamailio cfg :

                if (client_nat_test("3")){
                        xlog("L_INFO", "CALL RE-INVITE/UPDATE Nat DETECTED $ci\n");
                        force_rport();
                        fix_contact();
                        # Change Media ip address to public IP
                        if(nat_uac_test("8") && search("Content-type: application/sdp")) {
                                xlog("L_INFO", ">>> RE-INVITE/UPDATE CALL fixing SDP- NAT \n");
                                fix_nated_sdp("2");
                        }
                }
