I've a *much* better fix for this. Will submit once I've collected someone from the station!

Thanks, with your patch dnsmasq doesn't crash anymore when receiving odd
EDNS packets from dnseval.

And thanks for requesting the CVE - I thought about this too, as the bug
constitutes some kind of DoS issue, but since nobody else complained, I
suspected it to be some variation of PEBKAC on my part :)

Oh, I believe it was Juan Manuel requesting the CVE - thanks!
