should Unix refuse to execute writable binaries?

[Ernest Hua]

-------------------------------------------------------------------------------
Actually the real question is:

Should the Unix kernel refuse to execute binaries (or scripts) that are ...

    1.  setuid-ed plus group and/or world writable?
    2.  setgid-ed plus world writable?

It seems like a simple check that should be help ensure a more secure Unix.

Please E-mail replies and I will post a summary.
