3. Description:

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.

4. Solution:

Before applying this update, make sure all previously-released errata
relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to
use the Red Hat Network to apply this update are available at
