 fix potential buffer overflow

"Lead to unexpected behavior?" That is definately not the candor and
honesty the world expects from what may be the leading Linux
distribution, or any open source project. It reeks of proprietary
vendor risk whitewashing. Either you don't understand the problem
effectively, which is bad, or you are attempting to hide it, which is
also bad.

| Package        : heimdal Vulnerability  : missing input sanitising
| Problem-Type   : remote Debian-specific: no CVE ID         :
| CAN-2004-0472
|
| Evgeny Demidov discovered a potential buffer overflow in a Kerberos
| 4 component of heimdal, a free implementation of Kerberos 5.  The
| problem is present in kadmind, a server for administrative access
| to the Kerberos database.  This problem could perhaps be exploited
| to cause the daemon to read a negative amount of data which could
| lead to unexpected behaviour.
|
| For the stable distribution (woody) this problem has been fixed in
| version 0.4e-7.woody.9.
|
| For the unstable distribution (sid) this problem has been fixed in
| version 0.6.2-1.
|
| We recommend that you upgrade your heimdal and related packages.
