Description

If a maxctrl list sessions command is run when a connection has not yet completed the handshaking process, MaxScale may crash. In a production context, where clients come and go, it is not possible to know whether the handshaking process is in process or not. Thus any maxctrl list sessions command may cause MaxScale to crash.

The pointer where the connection attributes were read was not checked for nulless which resulted in the crash for sessions that were in the handshaking phase.
