TESO in.telnetd buffer overflow

Vulnerability Assessment Summary
Attempts to overflow the Telnet server buffer

when it receives a long sequence of 'Are You There' commands.
This probably means it overflows one of its internal buffers and
crashes. It is likely a possible hacker could abuse this bug to gain
control over the remote host's superuser.
