Descriptions
The SillMap::readFace function in FeatureMap.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, mishandles a return value, which allows remote attackers to cause a denial of service (missing initialization, NULL pointer dereference, and application crash) via a crafted Graphite smart font.
La función SillMap::readFace en FeatureMap.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 maneja correctamente el valor de retorno, lo que permite a atacantes remotos causar una denegación de servicio (falta inicialización, referencia a puntero NULL y caída de aplicación) 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.
