CVE-2019-8375

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).
