(RHSA-2011:0930) Moderate: NetworkManager security update

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.
