Description van der Kooij, Hugo 1999-09-10 05:54:32 UTC

Just forwarding this DoS that I reproduced on Red Hat Linux
6.0 for intel including all patches but the XFree86 ones
from September 7, 1999

"Hi,i found local DoS that Crash telnetd (tested on
Slackware 4.0, RH 5.2)
telnet localhost | telnet localhost | telnet localhost
...... about 50 times
result will be 'Connection Refused' , telnetd crash."

The riginal report was made on bugtraq

This is actually the standard inetd behavior...
