Information

SUSE operating system file systems that contain user home directories must be mounted to prevent files with the setuid and setgid bit set from being executed.

GROUP ID: V-234998
RULE ID: SV-234998r991589

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.

Solution

Configure the SUSE operating system "/etc/fstab" file to use the "nosuid" option on file systems that contain user home directories for interactive users.

Re-mount the filesystems.

sudo mount -o remount /home
