"In GNOME Shell through 45.7, a portal helper can be launched automatically (without user confirmation) based on 
network responses provided by an adversary (e.g., an adversary who controls the local Wi-Fi network), and subsequently 
loads untrusted JavaScript code, which may lead to resource consumption or other impacts depending on the JavaScript 
code's behavior.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
