Trying to "echo PASSWORD | su ACCOUNT" will elicit a response of
"standard in must be a tty..." therefore the sploit would stop on the
first word in the list as if it was the correct password. Therefore I fail
to see the exact sploit here. I tried this on a stock RH 6.1 machine.

this happens on a redhat 5.2:

[markus () balu markus]$ echo wrongpass | su -
Password: su: incorrect password
[markus () balu markus]$ echo rootpass | su -
Password: stdin: is not a tty

so there is a noticeable difference between the right password and the
wrong ones.

this is what redhat 6.1 tells me:

[md () serv md]$ echo wrongpass | su -
standard in must be a tty
[md () serv md]$ echo rightpass | su -
standard in must be a tty

seems like they fixed it.

regards, markus
