This issue was patched in ELSA-2015-2154.

NVD Description

Note: Versions mentioned in the description apply only to the upstream krb5-devel package and not the krb5-devel package as distributed by Oracle:7. See How to fix? for Oracle:7 relevant fixed versions and status.

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.
