Why in all this telnetd flap has nobody mentioned that /bin/login should
be relinked STATICALLY?  That at least defers the LD_* class of problem
until after login has done the setuid and exec, but still leaves things
like IFS passed to scripts.


Unfortunately, we can't do that.

Too much *requires* static dynamic linking, and in future even more
will be required. (Pluggable Authentication Modules)

BTW, login does filter other bad variables such as PATH, IFS and SHELL.
