Ispravljene su tri ranjivosti u programskom paketu libtiff koji se koristi za obradu TIFF (eng. Tagged Image File Format) slikovnih datoteka. Jedna od ranjivosti se očituje kao preljev međuspremnika, a druge dvije kao cjelobrojno prepisivanje u funkcijama "cvt_whole_image", "tiffcvt" i "TIFFroundup". Sve ranjivosti se mogu iskoristiti podmetanjem posebno oblikovane TIFF datoteke, a udaljenom napadaču omogućuju izvođenje DoS napada ili pokretanje proizvoljnog programskog koda. Korisnici se potiču na korištenje najnovije inačice.
