1. Summary:

An updated redhat-config-nfs package that fixes bugs and potential security issues is now available for Red Hat Enterprise Linux 3.

3. Problem description:

The redhat-config-nfs package includes a graphical user interface for creating, modifying, and deleting nfs shares.

John Buswell discovered a flaw in redhat-config-nfs that could lead to incorrect permissions on exported shares when exporting to multiple hosts. This could cause an option such as "all_squash" to not be applied to all of the listed hosts. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-0750 to this issue.

Additionally, a bug was found that prevented redhat-config-nfs from being run if hosts didn't have options set in /etc/exports.

All users of redhat-config-nfs are advised to upgrade to these updated packages as well as checking their NFS shares directly or via the /etc/exports file for any incorrectly set options.

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:
