Descriptions

The authentication_agent_new function in polkitbackend/polkitbackendinteractiveauthority.c in PolicyKit (aka polkit) before 0.113 allows local users to cause a denial of service (NULL pointer dereference and polkitd daemon crash) by calling RegisterAuthenticationAgent with an invalid object path.

La función authentication_agent_new en polkitbackend/polkitbackendinteractiveauthority.c en PolicyKit (también conocido como polkit) en versiones anteriores a 0.113 permite a usuarios locales provocar una denegación de servicio (referencia a puntero NULL y caída de demonio polkitd) llamando a RegisterAuthenticationAgent con una ruta de objeto no válida.
