do_tgs_req.c in the Key Distribution Center (KDC) in MIT Kerberos 5 (aka
krb5) 1.11 before 1.11.4, when a single-component realm name is used,
allows remote authenticated users to cause a denial of service (daemon
crash) via a TGS-REQ request that triggers an attempted cross-realm
referral for a host-based service principal.
