Descriptions

Code.cpp in Libgraphite in Graphite 2 1.2.4, as used in Mozilla Firefox before 43.0 and Firefox ESR 38.x before 38.6.1, does not consider recursive load calls during a size check, which allows remote attackers to cause a denial of service (heap-based buffer overflow) or possibly execute arbitrary code via a crafted Graphite smart font.

Code.cpp en Libgraphite en Graphite 2 1.2.4, como se utiliza en Mozilla Firefox en versiones anteriores a 43.0 y Firefox ESR 38.x en versiones anteriores a 38.6.1, no considera las llamadas recursivas de carga durante una comprobación de tamaño, lo que permite a atacantes remotos causar una denegación de servicio (desbordamiento d buffer basado en memoria dinámica) o posiblemente ejecutar código arbitrario a través de una fuente inteligente Graphite.

A vulnerability has been discovered in Graphite2. An attacker able to trick an unsuspecting user into opening specially crafted font files in an application using Graphite2 could exploit these flaws to cause the application to crash or, potentially, execute arbitrary code with the privileges of the application.
