1.227 OL09-00-002067

Information

OL 9 must mount /var/tmp with the nodev option.

GROUP ID: V-271663
RULE ID: SV-271663r1091701

The "nodev" mount option causes the system to not interpret character or block special devices. Executing character or block special devices from untrusted file systems increases the opportunity for nonprivileged users to attain unauthorized administrative access.

The only legitimate location for device files is the "/dev" directory located on the root partition, with the exception of chroot jails if implemented.

Solution

Configure OL 9 to mount /var/tmp with the nodev option.

Modify "/etc/fstab" to use the "nodev" option on the "/var/tmp" directory.
