Advisory ID: RHSA-2004:434-01

Updated on: 2004-09-22
Product: Red Hat Enterprise Linux
CVE Names: CAN-2004-0750
----------------------------------------------------------------------

1. Summary:

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

2. Relevant releases/architectures:

Red Hat Enterprise Linux AS version 3 - noarch
Red Hat Desktop version 3 - noarch
Red Hat Enterprise Linux ES version 3 - noarch
Red Hat Enterprise Linux WS version 3 - noarch

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,
