RHEL 2.1 : krb5 (RHSA-2002:250)

Critical Nessus Plugin ID 12331


The remote Red Hat host is missing one or more security updates.


A remotely exploitable stack-based buffer overflow has been found in the Kerberos v4 compatibility administration daemon distributed with the Red Hat Linux krb5 packages.

[Updated 09 Jan 2003] Added fixed packages for the Itanium (IA64) architecture.

Kerberos is a network authentication system.

A stack-based buffer overflow has been found in the implementation of the Kerberos v4 compatibility administration daemon (kadmind4), which is part of the MIT krb5 distribution. This vulnerability is present in version 1.2.6 and earlier of the MIT krb5 distribution and can be exploited to gain unauthorized root access to a KDC host. The attacker does not need to authenticate to the daemon to successfully perform this attack.

kadmind4 is included in the Kerberos packages in Red Hat Linux Advanced Server but is not enabled or used by default.

All users of Kerberos are advised to upgrade to these errata packages which contain a backported patch and are not vulnerable to this issue.


Update the affected packages.
