Moderate: NetworkManager security update

Updated NetworkManager packages that fix two security issues are now
available for Red Hat Enterprise Linux 5.

This update has been rated as having moderate security impact by the Red
Hat Security Response Team.

NetworkManager is a network link manager that attempts to keep a wired or
wireless network connection active at all times.

A missing network certificate verification flaw was found in
NetworkManager. If a user created a WPA Enterprise or 802.1x wireless
network connection that was verified using a Certificate Authority (CA)
certificate, and then later removed that CA certificate file,
NetworkManager failed to verify the identity of the network on the
following connection attempts. In these situations, a malicious wireless
network spoofing the original network could trick a user into disclosing
authentication credentials or communicating over an untrusted network.
(CVE-2009-4144)

An information disclosure flaw was found in NetworkManager's
nm-connection-editor D-Bus interface. If a user edited network connection
options using nm-connection-editor, a summary of those changes was
broadcasted over the D-Bus message bus, possibly disclosing sensitive
information (such as wireless network authentication credentials) to other
local users. (CVE-2009-4145)

Users of NetworkManager should upgrade to these updated packages, which
contain backported patches to correct these issues.

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