漏洞描述

In GNOME Shell through 45.2, unauthenticated remote code execution can be achieved by intercepting two DNS requests (GNOME Network Manager and GNOME Shell Portal Helper connectivity checks), and responding with attacker-specific IP addresses. This DNS hijacking causes GNOME Captive Portal to be launched via a WebKitGTK browser, by default, on the victim system; this can run JavaScript code inside a sandbox. NOTE: the vendor's position is that this is not a vulnerability because running JavaScript code inside a sandbox is the intended behavior.
