  "title": "Login-session token nonce reuse in Krill",
  "summary": "Krill versions before 0.16.1 can reuse encryption nonces for login-session tokens after a service restart. A network attacker with existing low-level access may be able to undermine the confidentiality or integrity of affected session tokens when the same encryption key remains in use across restarts.",
  "mitigation": "Upgrade Krill to version 0.16.1 or later. Until upgrading, reduce exposure by limiting access to the Krill service and minimizing restarts.",
