[getdns-users] Stubby: DoS possible under specific circumstances

Hello,

I've discovered a behavior in Stubby that can be abused for a Denial of 
Service (DoS) against Stubby. The circumstances under which this attack 
is possible are not very likely, so this is most probably not a major 
security risk. However, I don't want to post details about it here 
publicly. Is there another channel where I can share these details?

Thanks

Jonathan
