Add noexec Option to /run/shm Partition (Scored)
Set noexec on the shared memory partition to prevent programs from executing from there.
Parameter:
[]
Technical Mechanism:
Setting this option on a file system prevents users from executing programs from shared memory. This deters users from introducing potentially malicious software on the system.
Fix:
Edit the /etc/fstab file and add noexec to the fourth field (mounting options). Look for entries that have mount points that contain /run/shm. See the fstab(5) manual page for more information.
# mount -o remount,noexec /run/shm
