CVE-2019-8375

Priority
Description
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).
