This is the default value for /tmp.  If your permissions were not set
to this then somehow you managed to change them.

A beginner SA mistake is to untar stuff into /tmp as root.  This can change
permissions on /tmp and break your system.  Don't do it.  It's not obvious
and an easy to make mistake.
