Red Hat Security Advisory 2011-0930-01 - 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.
