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.
