Product: Red Hat Enterprise Linux
CVE Names: CAN-2004-1189
----------------------------------------------------------------------

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:
