CVE-2014-2241

Estado: ModificadaMedia (6.8)—

Las funciones (1) cf2_initLocalRegionBuffer y (2) cf2_initGlobalRegionBuffer en cff/cf2ft.c en FreeType anterior a 2.5.3 no comprueban debidamente si una subrutina existe, lo que permite a atacantes remotos causar una denegación de servicio (fallo de aserción), tal y como fue demostrado por un archivo ttf manipulado.
