SLEM 5 file systems that are used with removable media must be mounted to prevent files with the setuid and setgid bit set from being executed.

| Description | ||||
| 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 unprivileged users to attain unauthorized administrative access. | ||||

Check Text (C-261283r996330_chk)
Verify SLEM 5 file systems used for removable media are mounted with the "nosuid" option with the following command:
> more /etc/fstab
UUID=2bc871e4-e2a3-4f29-9ece-3be60c835222 /mnt/usbflash vfat noauto,owner,ro,nosuid 0 0
If a file system found in "/etc/fstab" refers to removable media and does not have the "nosuid" option set, this is a finding.
Fix Text (F-64920r995715_fix)
Configure SLEM 5 "/etc/fstab" file to use the "nosuid" option on file systems that are associated with removable media.
