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.

Security readout for executives and security teams

This is a privacy leak in GNOME NetworkManager: systems using VPNs could still send private DNS lookups to local network DNS servers. That can reveal destinations or internal hostnames to whoever controls or monitors the local DNS path. It is not described as code execution or privilege escalation. Linux desktops or servers using GNOME NetworkManager 1.10.2 or earlier with VPN DNS routing are the primary concern. Exposure depends on distribution packaging and resolver configuration. The source bundle does not provide complete vendor/product CPEs. Prioritize for environments relying on VPNs to protect sensitive browsing, internal hostnames, or regulated activity. It is not an emergency remote-code risk, but it can undermine VPN confidentiality and should be handled through endpoint inventory, vendor patch review, and DNS leak validation. Mitigation focus: Inventory NetworkManager versions on VPN-using Linux endpoints.; Review distribution advisories for NetworkManager DNS leak fixes.; Apply vendor-supported NetworkManager updates where available..
