1.213 OL09-00-002032

Information

OL 9 must prevent files with the setuid and setgid bit set from being executed on the /boot/efi directory.

GROUP ID: V-271649
RULE ID: SV-271649r1184198

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 nonprivileged users to attain unauthorized administrative access.

Solution

Configure OL 9 to prevent files with the setuid and setgid bit set from being executed on the /boot/efi directory.

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