U radu programskog paketa cups uočeno je i ispravljeno nekoliko sigurnosnih nedostataka. Cups je paket koji omogućuje uporabu pisača na operacijskim sustavima Unix/Linux. Neke od ranjivosti vezane su uz neispravnu obradu opisnika datoteka, neodgovarajuće upravljanje memorijom te dereferenciranje NULL pokazivača kod prikaza RSS obavijesti o završenom poslu, i sl. Lokalni i udaljeni zlonamjerni korisnici mogu ih iskoristiti za napad uskraćivanja usluge (eng. Denial of Service, DoS). Svim se korisnicima savjetuje detaljnije čitanje izvorne preporuke i primjena objavljenih rješenja kako bi ispravili uočene nedostatke.
