1. Summary:

Updated Kerberos (krb5) packages that correct a buffer overflow bug are now
available for Red Hat Enterprise Linux 4.

This update has been rated as having moderate security impact by the Red Hat
Security Response Team.

2. Relevant releases/architectures:

Red Hat Enterprise Linux AS version 4 - i386, ia64, ppc, ppc64, s390, s390x, x86_64
Red Hat Enterprise Linux Desktop version 4 - i386, x86_64
Red Hat Enterprise Linux ES version 4 - i386, ia64, x86_64
Red Hat Enterprise Linux WS version 4 - i386, ia64, x86_64

3. Problem description:

Kerberos is a networked authentication system that uses a trusted third
party (a KDC) to authenticate clients and servers to each other.

A heap based buffer overflow bug was found in the administration library of
Kerberos 1.3.5 and earlier.  This bug could allow an authenticated remote
attacker to execute arbitrary commands on a realm's master Kerberos KDC. 
The Common Vulnerabilities and Exposures project (cve.mitre.org) has
assigned the name CAN-2004-1189 to this issue.

All users of krb5 should upgrade to these updated packages, which contain
backported security patches to resolve these issues.

4. Solution:

Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.  Use Red Hat
Network to download and update your packages.  To launch the Red Hat
Update Agent, use the following command:

    up2date

For information on how to install packages manually, refer to the
following Web page for the System Administration or Customization
guide specific to your system:

    http://www.redhat.com/docs/manuals/enterprise/

5. Bug IDs fixed (http://bugzilla.redhat.com/):
