CVE-2017-7845

Estado: ModificadaAlta (8.8)—

Ocurre un desbordamiento de búfer cuando se dibujan y validan elementos usando Direct 3D 9 con la librería de gráficos ANGLE, utilizado para contenidos WebGL. Esto se debe a que se pasa un valor incorrecto en la librería durante las comprobaciones y resulta en un cierre inesperado potencialmente explotable. Nota: este ataque solo afecta a sistemas operativos Windows. Los otros sistemas operativos no se ven afectados. Esta vulnerabilidad afecta a las versiones anteriores a la 52.5.2 de Thunderbird, las versiones anteriores a la 52.5.2 de Firefox ESR y las versiones anteriores a la 57.0.2 de Firefox.
