    Vendor's Description:

    "ChatterBox is a multiple client, single server graphical chat
    program written in Java using Swing. Some basic features include
    sending private messages, kicking users (server only), and obtaining
    IP information on users (server only). It runs on any operating system
    supporting Java 1.3."

    2. The bug:
    ------------

    ChatterBox is not able to manage irregular requests in fact it
    will crash.

    xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

    -------------
    3. The code:
    -------------

    To test the vulnerability simply send to the chat server a string like:

    "aaaaaa"

    and the chat server will go down.

    4. The fix:
    ------------

    Vendor was contacted.
    Bug will be probably fixed in the next version of ChatterBox,
    so go on the ChatterBox's official website:
    http://www.urbancities.net/burton/ and check for a new version.
