The `org.rpm.dnf.v0.SessionManager.open_session` method takes a key/value map of configuration entries. A sub-entry in this map, placed under the \"config\" key, is another key/value map. The configuration values found in it will be forwarded as configuration overrides to the `libdnf5::Base` configuration.\u00a0\n\nPractically all libdnf5 configuration aspects can be influenced here. Already when opening the session via D-Bus, the libdnf5 will be initialized using these override configuration values. There is no sanity checking of the content of this \"config\" map, which is untrusted data.\u00a0It is possible to make the library loading a plug-in shared library under control of an unprivileged user, hence achieving root access.\u00a0\n\n"}, {"lang": "es", "value": "El exploit de ra\u00edz local a trav\u00e9s del diccionario de configuraci\u00f3n en dnf5daemon-server anterior a 5.1.17 permite que un usuario malintencionado afecte la confidencialidad y la integridad a trav\u00e9s del diccionario de configuraci\u00f3n. Hay problemas con la interfaz D-Bus mucho antes de que se invoque Polkit. El m\u00e9todo `org.rpm.dnf.v0.SessionManager.open_session` toma un mapa clave/valor de las entradas de configuraci\u00f3n. Una subentrada en este mapa, ubicada debajo de la clave \"config\", es otro mapa de clave/valor. Los valores de configuraci\u00f3n que se encuentran en \u00e9l se reenviar\u00e1n como anulaciones de configuraci\u00f3n a la configuraci\u00f3n `libdnf5::Base`. Aqu\u00ed se pueden influir pr\u00e1cticamente todos los aspectos de configuraci\u00f3n de libdnf5. Ya al abrir la sesi\u00f3n a trav\u00e9s de D-Bus, libdnf5 se inicializar\u00e1 utilizando estos valores de configuraci\u00f3n de anulaci\u00f3n.
