Description

According to the version of the NetworkManager packages installed, the EulerOS installation on the remote host is affected by the following vulnerability :

  • 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.(CVE-2018-1000135)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
