Check Text ( C-60155r1_chk )
To verify that binaries cannot be directly executed from the /tmp directory, run the following command: $ grep '\s/tmp' /etc/fstab The resulting output will show whether the /tmp partition has the "noexec" flag set. If the /tmp partition does not have the noexec flag set, this is a finding.

Fix Text (F-64775r1_fix)
The "noexec" mount option can be used to prevent binaries from being executed out of "/tmp". Add the "noexec" option to the fourth column of "/etc/fstab" for the line which controls mounting of "/tmp".
