The bug was that you could align the given password string so that it was at the end of a page boundary, and have the next page in the address space mapped to a non-existant page of a write-protected file. Normally, Tenex would create a page when you tried to access a non-existant page, but in this case it couldn't (since the file was write-protected).
So, you did a password-checking system call (e.g. the system call which tried to obtain owner access to another directory) set up in this way and you would get one of two failures: Incorrect Password meant that your prefix was wrong, Page Fault meant that your prefix was right but that you need more characters.
BTW have you tried to enter the Konami code into Reader?
