Keylime registrar
is prone to a simple denial of service attack in which an adversary opens a connection to the TLS port (by default, port 8891
) blocking further, legitimate connections. As long as the connection is open, the registrar
is blocked and cannot serve any further clients (agents
and tenants
), which prevents normal operation. The problem does not affect the verifier
.
Users should upgrade to release 7.4.0
