Vulnerability Discussion
The "/tmp" partition is used as temporary storage by many programs. Placing "/tmp" in its own partition enables the setting of more restrictive mount options, which can help protect programs that use it.
Check
Verify that a separate file system/partition has been created for "/tmp" with the following command:
$ mount | grep /tmp
tmpfs /tmp tmpfs noatime,mode=1777 0 0
If a separate entry for "/tmp" is not in use, this is a finding.
Fix
Migrate the "/tmp" path onto a separate file system.
