"A remote Denial of Service vulnerability was discovered in the heimdal
implementation of the telnet daemon. A remote attacker could force the
server to crash due to a NULL de-reference before the user logged in,
resulting in inetd turning telnetd off because it forked too fast.

Please note that the heimdal-servers package is not officially
supported in Ubuntu (it is in the 'universe' component of the
archive). However, this affects you if you use a customized version
built from the heimdal source package (which is supported).

Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
