Descriptions

The tt_cmap4_validate function in sfnt/ttcmap.c in FreeType before 2.5.4 validates a certain length field before that field's value is completely calculated, which allows remote attackers to cause a denial of service (out-of-bounds read) or possibly have unspecified other impact via a crafted cmap SFNT table.

La función tt_cmap4_validate en sfnt/ttcmap.c en FreeType anterior a 2.5.4 valida cierto campo de longitud antes de que el valor de este campo está calculado completamente, lo que permite a atacantes remotos causar una denegación de servicio (lectura fuera de rango) o posiblemente tener otro impacto no especificado a través de una tabla SFNT cmap manipulada.
