    I'm sorry you feel that way.

    There is no way, in this case, that a fix could be underway. ISS made
    it public 2hrs after sending a note to the ASF. I don't even know if
    they got a reply in that timeframe, nevermind something to the effect
    of "we're working on it right now".

    Nevertheless, what ISS did was very wrong. Not only did they disclose
    it far too early (24hrs would *not* have made a huge difference), but
    they advertised a fix that did not fix the problem entirely!

    So what would you rather have? A false sense of security in the bogus
    patch they released with their early advisory? Or 24hrs of ignorance,
    a time frame in which it is unlikely that we would see a large number
    of exploits being performed, nevermind created?

    Don't get me wrong, I'm all for public disclosure of bugs, whether
    they are currently fixed or not. But most people who find bugs give
    the authors a decent amount of time to provide a fix, and often
    coordinate with the author to release a statement. What ISS did is
    just plain ignorant.

    Yes. But you have to walk a fine line here. Do you let the entire
    world know of a problem without having discussed with the author at
    all? There is such a thing as etiquette in these circles, and it is
    *proper* for someone who has found a problem to discuss it with the
    author, or at least attempt to initiate discussion and wait for a
    reasonable period of time to pass before disclosing it to the general
    public. 2hrs is *not* reasonable, and I'm sure you'll agree despite
    your need/want for immediate disclosure. It does no one any good to
    know this... this advertisement of a problem before a fix is issued
    just gives crackers who may not have known about the problem the head
    start they need to start working on exploiting it before a fix is
    made.

    The only solution then is (in this specific case) use a faulty patch
    and believe you are secure when you're not, live with the possibility
    of the DoS, or shut down your server altogether.

    Yes, but security professionals have a responsibility that does not
    always conform to this statement. You make it too cut and dry without
    thinking of the consequences.
