    Please note that the version that does not work is the one created with
    MacroMedia software.  There is another version available that is not
    affected by this.

    Summary: "The Matrix" Windows 9.x/NT screensaver password protection
    doesn't work.
    
    This is *not* a major problem, especially for those folks who stick
    to guidelines and never install any screensavers that weren't supplied
    by Microsoft with Windows ;-).   In fact it hardly seems worth bothering
    Bugtraq with it, except that so many admins seem to be quite taken
    with "Matrix theory" ...
    
    [ I tried informing the owners of this "product" by emailing
    webmasterat_private, but my email was bounced (connection
    refused), so they've had their chance - other folks need to know. ]
    
    Copy of what I emailed to the authors of the "Matrix" screensaver available
    at http://www.whatisthematrix.com :

    Dear Whoever-runs-your-website,
    
    I just downloaded your Matrix screensaver for Windows 95/NT (for which :
    thanks) and having now tried it I feel I must bring to your attention a
    *serious* security bug in the screensaver :-
    
    Running on Windows 95 OSR2, if I set the "Password protected" screensaver
    option, then when the screen saver is running, if I move the mouse or press
    a key to wake the screensaver up, a password prompt appears as it should,
    but I can then simply press the "Escape" keyboard key and the screensaver
    terminates with no password required - aaaaggghh !
    
    Given the popularity of the Matrix film among computer industry people, I
    imagine many people are running the screensaver, and therefore are
    subjecting themselves to a significant risk of unauthorised access to
    their PCs. I decided I should inform you of the bug, to give you a chance
    to fix it, before I start publicising the risk in the regular security
    forums on
    the Internet.
