2003-03-17: Security advisory regarding v4 cross-realm All versions of the kerberos server are vulnerable to a protocol bug in the kerberos v4 cross-realm operation. Release 1.2.2 by default disables cross-realm in the server, and adds an option for enabling it. The long-term fix is to migrate to Kerberos v5.
