Discussion

The noexec mount option causes the system to not execute binary files. This option must be used for mounting any file system not containing approved binary files, as they may be incompatible. Executing files from untrusted file systems increases the opportunity for nonprivileged users to attain unauthorized administrative access.

Verify that OL 9 is configured to mount /dev/shm with the noexec option.

Verify "/dev/shm" is mounted with the "noexec" option with the following command:

$ mount | grep /dev/shm
tmpfs on /dev/shm type tmpfs (rw,nodev,nosuid,noexec,seclabel)

If the /dev/shm file system is mounted without the "noexec" option, this is a finding.
