                   Red Hat Security Advisory

Synopsis:          Low: coreutils security update
Advisory ID:       RHSA-2008:0780-01
Product:           Red Hat Enterprise Linux
Advisory URL:      https://rhn.redhat.com/errata/RHSA-2008-0780.html
Issue date:        2008-07-24
CVE Names:         CVE-2008-1946 
=====================================================================

1. Summary:

Updated coreutils packages that fix a security issue are now available for
Red Hat Enterprise Linux 4.

This update has been rated as having low security impact by the Red Hat
Security Response Team.

2. Relevant releases/architectures:

Red Hat Enterprise Linux AS version 4 - i386, ia64, ppc, 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. Description:

The coreutils package contains the core GNU utilities. It is the
combination of the old GNU fileutils, sh-utils, and textutils packages.

The coreutils packages were found to not use the pam_succeed_if Pluggable
Authentication Module (PAM) correctly in the configuration file for the
"su" command. Any local user could use this command to change to a
 locked
or expired user account if the target account's password was known to the
user running "su". These updated packages, correctly, only allow the
 root
user to switch to locked or expired accounts using "su".
 (CVE-2008-1946)

All users of coreutils are advised to upgrade to this updated package,
which resolve this issue.

4. Solution:

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