Vulnerability Assessment Details

RHSA-2002-250: krb

Vulnerability Assessment Summary
Check for the version of the krb packages

Detailed Explanation for this Vulnerability Assessment


A remotely exploitable stack 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 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.
