The kdcpreauth modules in MIT Kerberos 5 (aka krb5) 1.12.x and 1.13.x
before 1.13.2 do not properly track whether a client’s request has been
validated, which allows remote attackers to bypass an intended
preauthentication requirement by providing (1) zero bytes of data or (2) an
arbitrary realm name, related to plugins/preauth/otp/main.c and
plugins/preauth/pkinit/pkinit_srv.c.
