<!-- Release notes generated using configuration in .github/release.yml
at master -->

This tag includes the FTL v6.6.2 release which imports six upstream
`dnsmasq` security fixes, covering all publicly disclosed CVEs against
the dnsmasq 2.92/2.93 line. Patches are taken verbatim from
<https://thekelleys.org.uk/dnsmasq/CVE/>

Details here: <https://github.com/pi-hole/FTL/releases/tag/v6.6.2>

#### Upgrade impact

All six fixes are minimal, self-contained changes to the embedded
dnsmasq sources. No FTL-side configuration or API changes; users should
see no observable behavior change beyond the closed vulnerabilities.

Fix dnsmasq CVE publications by
[@&#8203;DL6ER](https://redirect.github.com/DL6ER) in
[pi-hole/FTL#2888](https://redirect.github.com/pi-hole/FTL/pull/2888)

This furthermore indirectly fixes
[#&#8203;2871](https://redirect.github.com/pi-hole/docker-pi-hole/issues/2871)
due to
[pi-hole/docker-base-images#158](https://redirect.github.com/pi-hole/docker-base-images/pull/158)
