Malicious takeover of previously owned ENS names

Impact

A user who owns an ENS domain can set a "trapdoor", allowing them to transfer ownership to another user, and later regain ownership without the new owner's consent or awareness.

Patches

A new ENS deployment is being rolled out that fixes this vulnerability in the ENS registry. The registry is newly deployed at 0x00000000000C2E074eC69A0dFb2997BA6C7d2e1e.

Workarounds

Do not accept transfers of ENS domains from other users on the old registrar.
