## Description

It was discovered that the IcedTea-Web used codebase attribute of the
<applet> tag on the HTML page that hosts Java applet in the Same Origin
Policy (SOP) checks. As the specified codebase does not have to match the
applet's actual origin, this allowed malicious site to bypass SOP via
spoofed codebase value.

Does enough of this package work today for this to still be a flaw?
