Hi guys, we've found a problem with return code of ssh_buffer_pack in ssh_message_global_request_reply_success (module server.c, version 0.7.0 and 0.7.1). This function is the only one in this module, where the return code (rc) of ssh_buffer_pack is checked against SSH_ERROR, but it must be checked against SSH_OK. I've marked the line 749 in the code below. int ssh_message_global_request_reply_success(ssh_message msg, uint16_t bound_port) { int rc; SSH_LOG(SSH_LOG_FUNCTIONS, "Accepting a global request"); if (msg->global_request.want_reply) { if (buffer_add_u8(msg->session->out_buffer , SSH2_MSG_REQUEST_SUCCESS) < 0) { goto error; } if(msg->global_request.type == SSH_GLOBAL_REQUEST_TCPIP_FORWARD && msg->global_request.bind_port == 0) { rc = ssh_buffer_pack(msg->session->out_buffer, "d", bound_port); ############# if (rc != SSH_ERROR) { ############# ssh_set_error_oom(msg->session); goto error; } } return packet_send(msg->session); } if(msg->global_request.type == SSH_GLOBAL_REQUEST_TCPIP_FORWARD && msg->global_request.bind_port == 0) { SSH_LOG(SSH_LOG_PACKET, "The client doesn't want to know the remote port!"); } return SSH_OK; error: return SSH_ERROR; } Best regards Andreas Gutschick ________________________________ NOTE: This e-mail (including any attachments) is for the sole use of the intended recipient(s) and may contain information that is confidential and/or protected by legal privilege.
