-Subject: [PATCH] Return only new keys in randkey [CVE-2014-5351]
-
-In kadmind's randkey operation, if a client specifies the keepold
-flag, do not include the preserved old keys in the response.
-
-CVE-2014-5351:
-
-An authenticated remote attacker can retrieve the current keys for a
-service principal when generating a new set of keys for that
-principal. The attacker needs to be authenticated as a user who has
-the elevated privilege for randomizing the keys of other principals.
-
-Normally, when a Kerberos administrator randomizes the keys of a
-service principal, kadmind returns only the new keys. This prevents
-an administrator who lacks legitimate privileged access to a service
-from forging tickets to authenticate to that service. If the
-"keepold" flag to the kadmin randkey RPC operation is true, kadmind
-retains the old keys in the KDC database as intended, but also
-unexpectedly returns the old keys to the client, which exposes the
-service to ticket forgery attacks from the administrator.
-
-A mitigating factor is that legitimate clients of the affected service
-will start failing to authenticate to the service once they begin to
-receive service tickets encrypted in the new keys. The affected
-service will be unable to decrypt the newly issued tickets, possibly
-alerting the legitimate administrator of the affected service.
