Summary: Updated lspp-eal4-config-ibm and capp-lspp-eal4-config-hp packages that fix a security issue are now available for Red Hat Enterprise Linux 5. This update has been rated as having important security impact by the Red Hat Security Response Team. 2. Description: The lspp-eal4-config-ibm and capp-lspp-eal4-config-hp packages contain utilities and documentation for configuring a machine for the Controlled Access Protection Profile, or the Labeled Security Protection Profile. It was discovered that use of the "capp-lspp-config" script results in the "/etc/pam.d/system-auth" file being set to world-writable. Authorized local users who have limited privileges could then exploit this to gain additional access, or to escalate their privileges. (CVE-2008-0884) This issue only affects users who have installed either of these packages from the Red Hat FTP site as their base system configuration kickstart script. New deployments using the lspp-eal4-config-ibm or capp-lspp-eal4-config-hp packages are advised to upgrade to these updated packages, which resolve this issue. For systems already deployed, the following command can be run as root to restore the permissions to a secure setting: chmod 0644 /etc/pam.d/system-auth 3. Solution: This update is available via the Red Hat FTP site. ftp://ftp.redhat.com/pub/redhat/linux/eal/EAL4_RHEL5/IBM/RPMS/lspp-eal4-config-ibm-0.65-2.el5.noarch.rpm ftp://ftp.redhat.com/pub/redhat/linux/eal/EAL4_RHEL5/HP/RPMS/capp-lspp-eal4-config-hp-0.65-2.el5.noarch.rpm 4.
