What is CVE-2018-1000135?

GNOME NetworkManager versions prior to 1.10.3 are vulnerable to an Information Exposure issue that can lead to the leakage of Private DNS queries to local network DNS servers while using a VPN. This flaw compromises user privacy, as sensitive DNS queries may be exposed, allowing malicious actors on the local network to track and analyze user activities. While some fixes were applied in specific Ubuntu 16.04 packages, subsequent updates removed these safeguards, leaving systems at risk. An upstream fix has not been made available, highlighting the need for urgent remediation steps.
