1.101 OL08-00-010571

Information

OL 8 must prevent files with the setuid and setgid bit set from being executed on the /boot directory.

GROUP ID: V-248617
RULE ID: SV-248617r991589

The "nosuid" mount option causes the system not to execute "setuid" and "setgid" files with owner privileges. This option must be used for mounting any file system not containing approved "setuid" and "setguid" files. Executing files from untrusted file systems increases the opportunity for unprivileged users to attain unauthorized administrative access.

Solution

Configure the "/etc/fstab" to use the "nosuid" option on the /boot directory.
