A flaw was found in NetworkManager in versions before 1.30.0. Setting match.path and activating a profile crashes NetworkManager. The highest threat from this vulnerability is to system availability.

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.

GNOME NetworkManager version 1.10.2 and earlier contains a Information Exposure (CWE-200) vulnerability in DNS resolver that can result in Private DNS queries leaked to local network's DNS servers, while on VPN. This vulnerability appears to have been fixed in Some Ubuntu 16.04 packages were fixed, but later updates removed the fix. cf. https://bugs.launchpad.net/ubuntu/+bug/1754671 an upstream fix does not appear to be available at this time.

GNOME NetworkManager allows remote attackers to cause a denial of service (IPv6 traffic disruption) via a crafted MTU value in an IPv6 Router Advertisement (RA) message, a different vulnerability than CVE-2015-8215.

GNOME NetworkManager before 0.8.6 does not properly enforce the auth_admin element in PolicyKit, which allows local users to bypass intended wireless network sharing restrictions via unspecified vectors.

The destroy_one_secret function in nm-setting-vpn.c in libnm-util in the NetworkManager package 0.8.999-3.git20110526 in Fedora 15 creates a log entry containing a certificate password, which allows local users to obtain sensitive information by reading a log file.

nm-connection-editor in NetworkManager (NM) 0.7.x exports connection objects over D-Bus upon actions in the connection editor GUI, which allows local users to obtain sensitive information by reading D-Bus signals, as demonstrated by using dbus-monitor to discover the password for the WiFi network.

NetworkManager (NM) 0.7.2 does not ensure that the configured Certification Authority (CA) certificate file for a (1) WPA Enterprise or (2) 802.1x network remains present upon a connection attempt, which might allow remote attackers to obtain sensitive information or cause a denial of service (connectivity disruption) by spoofing the identity of a wireless network.
