Descriptions

FreeType before 2.4.9, as used in Mozilla Firefox Mobile before 10.0.4 and other products, allows remote attackers to cause a denial of service (invalid heap write operation and memory corruption) or possibly execute arbitrary code via crafted glyph or bitmap data in a BDF font that lacks an ENCODING field.

FreeType antes de v2.4.9, tal como se utiliza en Mozilla Firefox Mobile antes de v10.0.4 y otros productos, permite a atacantes remotos causar una denegación de servicio (operación no válida de escritura y corrupción de memoria) o posiblemente ejecutar código arbitrario a través del glifo modificado o datos del mapa de bits en una fuente BDF que carece de campo ENCODING.
