Debian DSA-504-1 : heimdal - missing input sanitising

critical Nessus Plugin ID 15341

Synopsis

The remote Debian host is missing a security-related update.

Description

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.

Solution

Upgrade the heimdal and related packages.

For the stable distribution (woody) this problem has been fixed in version 0.4e-7.woody.9.
