Caldera OpenLinux advisory for sendmail
Author: JT Smith
Caldera has issued advisory number CSSA-2001-034.0 to detail a permission problem with the default setup of sendmail in all versions of its OpenLinux distribution. With the default settings left in place, a local attacker can start a DoS attack that will halt all mail delivery, or read the full headers of all messages in the mail queue.
