The finalize_with_tag API did not enforce a minimum tag length. If a
user did not validate the input length prior to passing it to
finalize_with_tag an attacker could craft an invalid payload with a
shortened tag (e.g. 1 byte) such that they would have a 1 in 256 chance
of passing the MAC check. GCM tag forgeries can cause key leakage
(CVE-2018-10903).");
