Detail

Problem Description:

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.

This update is available via Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at http://kbase.redhat.com/faq/FAQ_58_10188
