2.1023 - The system must mount /dev/shm with the nosuid option. - mount

Information

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 system so that /dev/shm is mounted with the 'nosuid' option.
