Summary
Red Hat Security Advisory: lspp-eal4-config-ibm and capp-lspp-eal4-config-hp security update

Notes

Topic
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.
Details
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
