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 explicitly.
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.
