Descriptions

GNOME NetworkManager before 0.8.6 does not properly enforce the auth_admin element in PolicyKit, which allows local users to bypass intended wireless network sharing restrictions via unspecified vectors.

GNOME NetworkManager antes de v0.8.6 G no aplica correctamente el elemento auth_admin de PolicyKit, lo que permite a usuarios locales eludir restricciones intencionadas en el intercambio de redes inalámbricas a través de vectores no especificados.

NetworkManager is a network link manager that attempts to keep a wired or wireless network connection active at all times. It was found that NetworkManager did not properly enforce PolicyKit settings controlling the permissions to configure wireless network sharing. A local, unprivileged user could use this flaw to bypass intended PolicyKit restrictions, allowing them to enable wireless network sharing. Users of NetworkManager should upgrade to these updated packages, which contain a backported patch to correct this issue. Running instances of NetworkManager must be restarted for this update to take effect. Various other issues were also addressed.
