Unix dosen't work without a root account. However, this sounds like a bug in Synaptic. It should _not_ be storing the previous password but only using a mechanism that will hash what you type and compare it with the password database.
Even if synaptic caches the password, it should not be able to make changes to the system (install/remove packages) with the old password. If it is, then most probably the machine might have been compromised.
