CVE-2014-9672

Error en el indice del array en la función parse_fond en base/ftmac.c en FreeType anterior a 2.5.4 permite a atacantes remotos causar una denegación de servicio (lectura fuera de rango) o obtener información sensible desde el proceso de la memoria a través de un recurso FOND manipulado en un fichero de fuentes Mac.

The tt_sbit_decoder_load_image function in sfnt/ttsbit.c in FreeType before 2.5.4 does not properly check for an integer overflow, which allows remote attackers to cause a denial of service (out-of-bounds read) or possibly have unspecified other impact via a crafted OpenType font. The tt_face_load_hdmx function in truetype/ttpload.c in FreeType before 2.5.4 does not establish a minimum record size, which allows remote attackers to cause a denial of service or possibly have unspecified other impact via a crafted TrueType font. The tt_face_load_kern function in sfnt/ttkern.c in FreeType before 2.5.4 enforces an incorrect minimum table length, which allows remote attackers to cause a denial of service or possibly have unspecified other impact via a crafted TrueType font. Various other issues have also been addressed.
