Bug: MSet allows you to change the name of a PC, and can set names to nothing.
Danger: MAXIMUM
Found by: Orion Elder

[build.c]
In do_mset find:

    if ( !str_cmp( arg2, "name" ) )
    {
        if ( !can_mmodify( ch, victim ) )
          return;
        if ( !IS_NPC(victim) && get_trust( ch ) < LEVEL_MASTER )
        {
            send_to_char( "Not on PC's.\n\r", ch );
            return;
        }


Change that to:

    if ( !str_cmp( arg2, "name" ) )
    {
        if ( !can_mmodify( ch, victim ) )
          return;
        if ( !IS_NPC( victim ) )
        {
            send_to_char( "Not on PC's.\n\r", ch );
            return;
        }


And below it add:

        if ( !arg3 || arg3[0] == '\0' )
        {
            send_to_char( "Names can not be set to an empty string.\n\r", ch );
            return;
        }


This has several potential problems. An empty name string makes for something that can not be targetted, first of al, and could case major problems. Being able to MSet a PCs name allows one to change their name to one that is already taken (thus resulting in confusion).

PCRename is made for that task anyway.
