Description OSIDB Bzimport 2025-11-24 14:59:01 UTC 
The Keylime registrar allows registration of another agent (different TPM device, different EK certificate) with a duplicate UUID.
This presents a critical security vulnerability that allows an attacker to take over an existing agent's identity by re-registering with the same UUID though a different TPM's EK certificate.
