Descriptions

gfx/2d/DataSurfaceHelpers.cpp in Mozilla Firefox before 41.0 on Linux improperly attempts to use the Cairo library with 32-bit color-depth surface creation followed by 16-bit color-depth surface display, which allows remote attackers to obtain sensitive information from process memory or cause a denial of service (out-of-bounds read) by using a CANVAS element to trigger 2D rendering.

Vulnerabilidad en gfx/2d/DataSurfaceHelpers.cpp en Mozilla Firefox en versiones anteriores a 41.0 en Linux, intenta utilizar indebidamente la librería Cairo con la creación de 32 bits de profundidad de color seguido por la muestra de 16 bits de profundidad de color de pantalla, lo que permite a atacantes remotos obtener información sensible de memoria de proceso o provocar una denegación de servicio (lectura fuera de rango) mediante el uso de un elemento CANVAS para desencadenar un renderizado 2D.
