VULHUB ™

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.
