OL 9 must mount /dev/shm with the nosuid option.

The "nosuid" mount option causes the system to not 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.

Verify that OL 9 is configured to mount /dev/shm with the nosuid option.

Verify "/dev/shm" is mounted with the "nosuid" option with the following command:

$ mount | grep /dev/shm tmpfs on /dev/shm type tmpfs (rw,nodev,nosuid,noexec,seclabel)

If the /dev/shm file system is mounted without the "nosuid" option, this is a finding.

Configure OL 9 to mount /dev/shm with the nosuid option.

Modify "/etc/fstab" to use the "nosuid" option on the "/dev/shm" file system.
