Haavatavuse ilmnemise p\u00f5hjuseks oli v\u00f5tme loomise protsessis kasutamine «b.putByte(String.fromCharCode(next & 0xFF))», samas kui meetodis putByte kutsuti veel kord v\u00e4lja meetod fromCharCode. Kahekordne meetodi fromCharCode kutsumine («String.fromCharCode( String.fromCharCode(next & 0xFF) )») viis selleni, et suur osa energia allika bufrist t\u00e4ideti nullidega, st v\u00f5ti genereeriti «juhuslikest» andmetest, mis koosnesid 97% nullidest.
