NetworkManager security update (RHSA-2010-0108)

Original Release Date: April 29, 2010
Last Revised: December 21, 2011
Number: ASA-2010-112
Risk Level: Low
Advisory Version: 2.0
Advisory Status: Final

1. Overview:

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. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2009-4144 to this issue.

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. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2009-4145 to this issue.

More information about these vulnerabilities can be found in the security advisory issued by RedHat Linux:

2. Avaya System Products on RHEL5 with NetworkManager installed:

Product: Affected Version(s): Risk Level: Actions:
Avaya Aura™ System Manager 5.x Low Upgrade SMGR to 6.1 or later

Recommended Actions for System Products:
Avaya strongly recommends that customers follow networking and security best practices by implementing firewalls, ACLs, physical security or other appropriate access restrictions. Though Avaya believes such restrictions should always be in place; risk to Avaya's product and the surrounding network from this potential vulnerability may be mitigated by ensuring these practices are implemented until such time as a product update is available or the recommended action is applied. Further restrictions as deemed necessary based on the customer's security policies may be required during this interim period.

3. Avaya Software-Only Products:

Avaya software-only products operate on general-purpose operating systems. Occasionally vulnerabilities may be discovered in the underlying operating system or applications that come with the operating system.

In the case of this advisory Avaya software-only products are not affected by the vulnerability directly but the underlying Linux platform may be. Customers should determine on which Linux operating system the product was installed and then follow that vendor's guidance.
