SYN flood denial of service attack

VOTE:  MODIFY

We sort of explain most vulnerabilities, at least to a minimum degree. 
To remain consistent, we should have some detail of this one too.
Something like - 
A destination system that fails to receive an ACK signal, after replying
to a SYN packet with a SYN/ACK packet, has reserved memory for the TCP
connection state until the connection times out.  Multiple rapid
occurrences of these initial SYN packets that remain unacknowledged will
result in a denial of service when the maximum number of TCP connections
has been reached (SYN Flood).

Reference: XF:nfs-portmap

The portmapper may act as a proxy and redirect service requests from
an attacker, making the request appear to come from the local host,
possibly bypassing authentication that would otherwise have taken
place.  For example, NFS file systems could be mounted through the
portmapper despite export restrictions.
