Description TEJ RATHI 2022-03-17 06:57:14 UTC

Hello Team, please check the below report:
--------

Keylime does not enforce that the agent registrar data is the same when the tenant uses it for validation of the EK and identity quote and the verifier for validating the integrity quote.

This allows an attacker to use one AK, EK pair from a real TPM to pass EK validation and give the verifier an AK of a software TPM.

Affects all versions of Keylime <6.4.0

Thanks
