Descriptions

The hb_buffer_ensure function in hb-buffer.c in HarfBuzz, as used in Pango 1.28.3, Firefox, and other products, does not verify that memory reallocations succeed, which allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) or possibly execute arbitrary code via crafted OpenType font data that triggers use of an incorrect index.

La función hb_buffer_ensure en hb-buffer.c de HarfBuzz, como el usuado en Pango v1.28.3,Firefox otros productos, no verifica que las reasignaciones de memoria sean exitosas, lo que permite a atacantes remotos provocar una denegación de servicio (desreferenciar el puntero a NULL y bloqueo de la aplicación) o posiblemente ejecutar código arbitrario a través de datos manipulados con fuente OpenType que provoca el uso de un índice incorrecto.
