Information

OL 9 must mount /tmp with the nosuid option.

GROUP ID: V-271655
RULE ID: SV-271655r1091677

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.

Solution

Configure OL 9 to mount /tmp with the nosuid option.

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