Kulumikizananso kumapangitsa kuti kusamuka kwa ntchito kumalaibulale kusakhale kodziwikiratu, zomwe zimapangitsa kuti zikhale zovuta kupanga zabwino pogwiritsa ntchito njira zobwereranso (ROP). Pogwiritsa ntchito njira ya ROP, wowukirayo samayesa kuyika nambala yake pamtima, koma amagwiritsa ntchito zidutswa zamakina zomwe zilipo kale m'malaibulale odzaza, kutha ndi malangizo obwerera (monga lamulo, awa ndi malekezero a ntchito za library) . Ntchito yogwiritsa ntchitoyo imatsikira pakumanga ma foni angapo ku midadada yofananira ("zida zamagetsi") kuti mupeze zomwe mukufuna.
