                   Red Hat Security Advisory

Synopsis:          Moderate: ncpfs security update
Advisory ID:       RHSA-2005:371-01
Advisory URL:      https://rhn.redhat.com/errata/RHSA-2005-371.html
Issue date:        2005-05-17
Updated on:        2005-05-17
Product:           Red Hat Enterprise Linux
CVE Names:         CAN-2005-0013
---------------------------------------------------------------------

1. Summary:

An updated ncpfs package is now available.

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 (Advanced Server) version 2.1 - i386, ia64
Red Hat Linux Advanced Workstation 2.1 - ia64
Red Hat Enterprise Linux ES version 2.1 - i386

3. Problem description:

Ncpfs is a file system that understands the Novell NetWare(TM) NCP
protocol.

A bug was found in the way ncpfs handled file permissions. ncpfs did not
sufficiently check if the file owner matched the user attempting to access
the file, potentially violating the file permissions. The Common
Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name
CAN-2005-0013 to this issue.

All users of ncpfs are advised to upgrade to this updated package, which
contains backported fixes for this issue.

4. Solution:

Before applying this update, make sure all previously released errata
relevant to your system have been applied.

To update all RPMs for your particular architecture, run:

rpm -Fvh [filenames]

where [filenames] is a list of the RPMs you wish to upgrade.  Only those
RPMs which are currently installed will be updated.  Those RPMs which are
not installed but included in the list will not be updated.  Note that you
can also use wildcards (*.rpm) if your current directory *only* contains
the
desired RPMs.

Please note that this update is also available via Red Hat Network.  Many
people find this an easier way to apply updates.  To use Red Hat Network,
launch the Red Hat Update Agent with the following command:

up2date

This will start an interactive process that will result in the appropriate
RPMs being upgraded on your system.
