It was found that nmcli, a command line interface to NetworkManager did not honour 802-1x.ca-path and 802-1x.phase2-ca-path settings, when creating a new profile. When a user connects to a network using this profile, the authentication does not happen and the connection is made insecurely.
NetworkManager 0.9 and earlier allows local users to use other users' certificates or private keys when making a connection via the file path when adding a new connection.
NetworkManager 0.9.x does not pin a certificate's subject to an ESSID when 802.11X authentication is used.
In NetworkManager 0.9.2.0, when a new wireless network was created with WPA/WPA2 security in AdHoc mode, it created an open/insecure network.
Format string vulnerability in the nminfohandler function in Network Manager may allow remote attackers to execute arbitrary code via format string specifiers in a Wireless Access Point identifier, which is not properly handled in a syslog call.
