            Description

            When an application implements a TCP Server using the LwIP socket interface functions, the sockets of the backlog may be corrupted during calling LwIP_Socket_Abort() or LwIP_Socket_Close(). The problem occurs when a SYN for the listening socket is received at the same time the socket is aborted or closed.
