    STATUS: QNX Software Systems Ltd was contacted on November 11, 2002.
    I received prompt replies and was assured that this was being sent through
    the proper channels to have this resolved. I was unable to receive a
    preliminary patch or a estimate as to how long this process would take.
    
    
    DESCRIPTION
    QNX Photon has a clipboard feature that enables you to cut and paste amongst
    other things. It has a security issue that allows anyone to access what 
    is on
    the clipboard.
    
    
    ISSUE
    /var/clipboard/localhost/00000000/1.TEXT holds the information you cut or
    copied. The name localhost may be different depending on the hostname of the
    system QNX Photon is installed on.
    The 00000000 signifies the user ID in hex. By changing this value, you can
    change whose information you see.
    1.TEXT holds the information.
    
    
    SYSTEM INFORMATION:
    QNX 6.2.0 Non-commercial edition on a x86 architecture was used. All patches
    and updates were applied at the time of writing.
    
    
    FIX
    Adjust permissions of the seperate user folders within
    /var/clipboard/localhost to only allow a individual to access their own
    clipboard.
