Synopsis:          Moderate: NetworkManager security update
Advisory ID:       RHSA-2011:1338-01
Product:           Red Hat Enterprise Linux
Advisory URL:      https://access.redhat.com/errata/RHSA-2011:1338.html
Issue date:        2011-09-26
CVE Names:         CVE-2011-3364 
====================================================================
1. Summary:

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.

3. Description:

NetworkManager is a network link manager that attempts to keep a wired or
wireless network connection active at all times. The ifcfg-rh
NetworkManager plug-in is used in Red Hat Enterprise Linux distributions to
read and write configuration information from the
/etc/sysconfig/network-scripts/ifcfg-* files.

An input sanitization flaw was found in the way the ifcfg-rh NetworkManager
plug-in escaped network connection names containing special characters. If
PolicyKit was configured to allow local, unprivileged users to create and
save new network connections, they could create a connection with a
specially-crafted name, leading to the escalation of their privileges.
Note: By default, PolicyKit prevents unprivileged users from creating and
saving network connections. (CVE-2011-3364)

Red Hat would like to thank Matt McCutchen for reporting this issue.

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
https://access.redhat.com/kb/docs/DOC-11259
