Vulnerability details

The vulnerability allows a remote attacker to perform DNS cache poisoning attacks.

The vulnerability exists due to an error within the TTL() function in plugin/etcd/etcd.go, which casts the 64-bit etcd lease ID to a uint32 and uses it as the TTL, resulting in cache pinning for very long periods. A remote attacker can perform DNS cache poisoning attack.
