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.
