[$] How to (not) fix a security flaw

<p>
A pair of flaws in the web interface for two small-business Cisco routers
make for a prime example of the wrong way to go about security fixes.
These kinds of flaws are, sadly, fairly common, but the comedy of errors
that resulted here is, thankfully, rather rare. Among other things, it
shows that
vendors may wish to await a
real fix rather than to release a small, ineffective band-aid to try to close
a gaping hole.
