Descriptions

The RenderTable::simplifiedNormalFlowLayout function in core/rendering/RenderTable.cpp in Blink, as used in Google Chrome before 40.0.2214.91, skips captions during table layout in certain situations, which allows remote attackers to cause a denial of service (out-of-bounds read) via unspecified vectors related to the Fonts implementation.

La función RenderTable::simplifiedNormalFlowLayout en core/rendering/RenderTable.cpp en Blink, usado en Google Chrome anterior a 40.0.2214.91, en ciertas situaciones, se salta los subtítulos durante el diseño de tabla, lo que permite a atacantes remotos causar una denegación de servicio (lectura fuera de rango) a través de vectores no especificados en la implementación Fonts.
