The remote Fedora host is missing a security update.
From dnsmasq's CHANGELOG :
Add code to make behaviour for TCP DNS requests that same as for UDP
requests, when a request arrives for an allowed address, but via a
banned interface. This change is only active on Linux, since the
relevant API is missing (AFAIK) on other platforms.
- dnsmasq now answers local queries if --except-interface
lo is used (libvirt's use case).
- dnsmasq is now built with $RPM_OPT_FLAGS, $RPM_LD_FLAGS
Note that Tenable Network Security has extracted the preceding
description block directly from the Fedora security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.
