Changes in Heimdal 7.5:

 Security

 - Fix CVE-2017-17439, which is a remote denial of service
   vulnerability:

     In Heimdal 7.1 through 7.4, remote unauthenticated attackers
     are able to crash the KDC by sending a crafted request
     containing empty data fields for client name or realm.

 Bug fixes

 - Handle long input lines when reloading database dumps.

 - In pre-forked mode (default on Unix), correctly clear the
   process ids of exited children, allowing new child processes
   to replace the old.

 - Fixed incorrect KDC response when no-cross realm TGT exists,
   allowing client requests to fail quickly rather than time
   out after trying to get a correct answer from each KDC.
