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

My workaround is to only call memset if the difference between buffer begin

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!
