Descriptions

debian/tor.init in the Debian tor_0.2.9.11-1~deb9u1 package for Tor was designed to execute aa-exec from the standard system pathname if the apparmor package is installed, but implements this incorrectly (with a wrong assumption that the specific pathname would remain the same forever), which allows attackers to bypass intended AppArmor restrictions by leveraging the silent loss of this protection mechanism. NOTE: this does not affect systems, such as default Debian stretch installations, on which Tor startup relies on a systemd unit file (instead of this tor.init script).

El archivo debian/tor.init en el paquete tor_0.2.9.11-1-deb9u1 de Debian para Tor, fue creado para ejecutar aa-exec desde el pathname (nombre de ruta) del sistema estándar si el paquete apparmor está instalado, pero implementa esto inapropiadamente (con una suposición inapropiada de que el pathname (nombre de ruta) específico sigue siendo el mismo siempre), lo que permite a los atacantes omitir las restricciones previstas de AppArmor mediante la explotación de la pérdida silenciosa de este mecanismo de protección. NOTA: esto no afecta a los sistemas, como las instalaciones de extensión de Debian por defecto, en las que el inicio de Tor se basa en un archivo de unidad systemd (en lugar de este script tor.init).
