Function pjsip_rx_data_clone has invalid dst->msg_info.msg_buf pointer.
It points to dst->pkt_info.packet and ignores offset of
*src->msg_info.msg_buf
*from src->pkt_info.packet.
Some modules (for example pjsua_lib) is using this method to notify
account with incoming call and end-user application can see only part of
invite in the end of message and some stuff in the beginning.
I think, that validation of src->msg_info.msg_buf (that it points to*
dst->pkt_info.packet*) is not required because msg_buf assignment is doing
only in *pjsip_tpmgr_receive_packet *and in
pjsip_rx_data_clone.
Patch in attachement.
