I have the packages in for testing, though repro may take some time to occur organically. I also think it might be prudent to add a Restart =on-failure directive to the systemd units regardless of whether the fix for this issue is effective, so that future bugs don't take down users' networks.

This looks like a possible use-after-free so likely has a security impact (at a minimum it is a denial of service due to the crash, especially if it can be triggered remotely) - I've reported it to ISC as such who will hopefully assign a CVE and then we can fix it as a security update. For future
