OVERVIEW

        A vulnerability has been identified in Gnome network-manager-applet 
        version 0.7.2.


IMPACT

        The vendor has provided the following information regarding this
        vulnerability:
        
        "If a connection was created with a CA certificate, but the user later 
        moved or deleted that CA certificate, the applet would simply provide 
        the connection to NetworkManager without any CA certificate. This could 
        cause NM to connect to the original network (or a network spoofing the 
        original network) without verifying the identity of the network as the 
        user expects." [1]


MITIGATION

        The vendor has provided a solution in the GIT source code 
        repository. [1]
