A NULL pointer dereference flaw was found in the procedure used by the MIT Kerberos kadmind service to store policies: the kadm5_create_principal_3() and kadm5_modify_principal() function did not ensure that a policy was given when KADM5_POLICY was set. An authenticated attacker with permissions to modify the database could use this flaw to add or modify a principal with a policy set to NULL, causing the kadmind service to crash.
