The coreutils package contains the core GNU utilities. It is thecombination of the old GNU fileutils, sh-utils, and textutils packages.The coreutils packages were found to not use the pam_succeed_if PluggableAuthentication Module (PAM) correctly in the configuration file for the"su" command. Any local user could use this command to change to a lockedor expired user account if the target account's password was known to theuser running "su". These updated packages, correctly, only allow the rootuser 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.
