MetricsAV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
clean client() in lib/rpc/svc auth gssapi.c in MIT Kerberos 5 (aka krb5) restarts its scan from the head of the client list after each removal, resulting in quadratic CPU cost. Remote attackers can cause a denial of service (CPU consumption in kadmind) by accumulating a large number of AUTH GSSAPI client entries.
