CVE-2022-23220 Information

Description

USBView 2.1 before 2.2 allows some local users (e.g. ones logged in via SSH) to execute arbitrary code as root because certain Polkit settings (e.g. allow_any=yes) for pkexec disable the authentication requirement. Code execution can for example use the –gtk-module option. This affects Ubuntu Debian and Gentoo.
