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. • http://cgit.freedesktop.org/harfbuzz/commit/?id=a6a79df5fe2ed2cd307e7a991346faee164e70d9 http://lists.fedoraproject.org/pipermail/package-announce/2011-March/056065.html http://lists.opensuse.org/opensuse-security-announce/2011-04/msg00000.html http://secunia.com/advisories/43559 http://secunia.com/advisories/43572 http://secunia.com/advisories/43578 http://secunia.com/advisories/43800 http://securitytracker.com/id?1025145 http://www.debian.org/security/2011/dsa-2178 http://www.mandriva.com/security& •
