Ubuntu Security Notice (C) 2006-2013 Canonical, Inc. / NASL script (C) 2006-2013 Tenable Network Security, Inc.
The remote Ubuntu host is missing one or more security-related patches.
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).
Update the affected packages.
