Synopsis :

The remote Red Hat host is missing one or more security updates.

Description :

Updated NetworkManager packages that fix one security issue are now
available for Red Hat Enterprise Linux 6.

The Red Hat Security Response Team has rated this update as having
moderate security impact. A Common Vulnerability Scoring System (CVSS)
base score, which gives a detailed severity rating, is available from
the CVE link in the References section.

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.
