I have backported the patches and have some packages to test in the security team PPA here:
https://launchpad.net/~ubuntu-security- proposed/+archive/ubuntu/ppa/+packages Could you please see if they solve the issue for you? Once you've tried them, I will release them as a security regression fix. Thanks! -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to dnsmasq in Ubuntu. https://bugs.launchpad.net/bugs/1916462 Title: dnsmasq failed to send packet: Network is unreachable Status in dnsmasq package in Ubuntu: New Bug description: the log shows this: Feb 22 09:37:53 myserver dnsmasq[2259]: failed to send packet: Network is unreachable repeatedly and frequently. This is a known bug in dnsmasq and has been fixed upstream (according to the thread quoted below). Apparently it is IPv6 related and triggered by Windows and Mac clients. An extensive thread on the subject is here on the OpenWRT forum: https://forum.openwrt.org/t/security-advisory-2021-01-19-1-dnsmasq- multiple-vulnerabilities/85903/123 I think this has been reported in the fallout of the quoted security vulnerabilities.
