The tcpd process name is specified by the super-user in the
inetd.conf file, which is owned by the super-user.

If an attacker can replace the tcpd process name in the inetd.conf
file, then your system has suffered a total breach of security.

The other claims are even more bogus (the poster overlooks that
null-terminated strings are shorter than their containing buffer).

Waste no time on this.
