Descriptions

The UIProcess subsystem in WebKit, as used in WebKitGTK through 2.23.90 and WebKitGTK+ through 2.22.6 and other products, does not prevent the script dialog size from exceeding the web view size, which allows remote attackers to cause a denial of service (Buffer Overflow) or possibly have unspecified other impact, related to UIProcess/API/gtk/WebKitScriptDialogGtk.cpp, UIProcess/API/gtk/WebKitScriptDialogImpl.cpp, and UIProcess/API/gtk/WebKitWebViewGtk.cpp, as demonstrated by GNOME Web (aka Epiphany).

El subsistema UIProcess en WebKit, tal y como se utiliza en WebKitGTK, hasta la versión 2.23.90, y WebKitGTK+, hasta la versión 2.22.6 y otros productos, no evita que el tamaño del diálogo del script sobrepase el tamaño de la vista web, lo que permite que los atacantes remotos provoquen una denegación de servicio (desbordamiento de búfer) o, posiblemente, otro tipo de impacto sin especificar. Esto está relacionado con UIProcess/API/gtk/WebKitScriptDialogGtk.cpp, UIProcess/API/gtk/WebKitScriptDialogImpl.cpp y UIProcess/API/gtk/WebKitWebViewGtk.cpp, tal y como queda demostrado por GNOME Web (también conocido como Epiphany).
