you can use expect's passmass script, or construct more simple one like :

Code:
#!/usr/bin/expect

set timeout -1
spawn ssh@host
expect "password:"
send "the-pass-goes-here\r"
sleep 1
spawn passwd [lindex $argv 0]
set password [lindex $argv 1]
expect "password:"
send "$password\r"
expect "password:"
send "$password\r"
expect eof
exit

This will, however, pose a security risk, by enclosing password in plain file.
I copied this example from http://floppsie.comp.glam.ac.uk/Glam...ripting/5.html, you will find great examples of Expect and scripting explanation.
