5efb452 by Guy Harris (guy@xxxxxxxxxxxx):

    Fix packet length handling.
    
    Treat the packet length as unsigned - it shouldn't be negative in the
    file.  If it is, that'll probably cause the sscanf to fail, so we'll
    report the file as bad.
    
    Check it against WTAP_MAX_PACKET_SIZE to make sure we don't try to
    allocate a huge amount of memory, just as we do in other file readers.
    
    Use the now-validated packet size as the length in
    ws_buffer_assure_space(), so we are certain to have enough space, and
    don't allocate too much space.
