CVE-2022-23220

Estado: ModificadaAlta (7.8)—

USBView versiones 2.1 anteriores a 2.2, permite a algunos usuarios locales (por ejemplo, los que son conectados por SSH) ejecutar código arbitrario como root porque determinadas configuraciones de Polkit (por ejemplo, allow_any=yes) para pkexec deshabilitan el requisito de autenticación. Una ejecución de código puede, por ejemplo, usar la opción --gtk-module. Esto afecta a Ubuntu, Debian y Gentoo
