Simply running etcdctl --endpoints http://hostname:port lock /test ls is enough to trigger this.

is this already fixed by #12106?

The fix is in 3.5 and 3.4.10. I don't think it was backported to 3.3.x branch.

Can you updated etcd to 3.4 or downgrade protobuf version used together with 3.3 ?

I cannot immediately upgrade to 3.4.

I am using your binary builds of 3.3; if you release a new 3.3 with a an older protobuf, then I'll gladly use it...

I confirm hitting the same bug. In our case, 3.3.x is used because of kubespray deployment of etcd.

For the time being, I have downgraded to 3.3.22 which seems to work fine.

3.3.23 has security fix for CVE-2020-15106 and CVE-2020-15112, could we backport #12000 (#12106) to 3.3?
