Descriptions

The getImageData function in the ImageBufferCairo class in WebCore/platform/graphics/cairo/ImageBufferCairo.cpp in WebKit, as used in WebKitGTK+ prior to version 2.20.3 and WPE WebKit prior to version 2.20.1, is vulnerable to a heap-based buffer overflow triggered by an integer overflow, which could be abused by crafted HTML content.

La función getImageData en la clase ImageBufferCairo en WebCore/platform/graphics/cairo/ImageBufferCairo.cpp en WebKit, tal y como se emplea en WebKitGTK+ en versiones anteriores a la 2.20.3 y WPE WebKit en versiones anteriores a la 2.20.1, es vulnerable a un desbordamiento de búfer basado en memoria dinámica (heap) desencadenado por un desbordamiento de enteros, que podría ser empleado por contenido HTML manipulado.
