I fail to see how this is a security concern; if you can *set* the alias to
begin with, why not just deep-six the whole thing right off? That is, you
still can only kill your files, and not the whole system. Unless you's are
arguing that some other user sets this and then root runs it, but that is the
age-old rule about root not being allowed to run user-controllable files and
users not being able to access system files for write access to begin with...
