Red Hat has recently released a Security Advisory (RHSA-1999:030-01)
covering a reverse denial of service bug in the vixie cron package.
As user you could restart sendmail even if the host should not receive
mail through the SMTP port.
Further investigation of Caldera and Debian discovered that it was
even worse. Red Hat did find a root exploit but didn' notice. When
sending a mail to the user Vixie Cron ran as root, not checking the
mail address that was passed to sendmail on the commandline.
We recommend you upgrade your cron package immediately.
wget url
will fetch the file for you
dpkg -i file.deb
will install the referenced file.
