Details

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.

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
