The fact that 'su' reads the password from stdin allows any
user to fake a login prompt and collect other users'
passwords. I've not been able to get a shell out of this
bug, but execution of commands as another user is indeed
Solution: compile 'su' so that it does not read the password
from stdin (as other dists do)
Erik please verify if this is incorrect, and please close it if so.
Christian, look at this and verify that is incorrect, if so then
please close it.
fixed in sh-utils-1.16-18
