RHSA-2010:0108 - Moderate: NetworkManager security update

Synopsis

Moderate: NetworkManager security update

Type/Severity

Security Advisory Moderate

Topic

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.

Description

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.
