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. (CVE-2011-2176)
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 (‘service NetworkManager restart’) for this update to take effect.
