Description:

   This update for libheimdal to version 7.5.0 fixes the following issues:

   The following security vulnerability was fixed:

   - CVE-2017-17439: Fixed a remote denial of service vulnerability through
     which remote unauthenticated attackers were able to crash the KDC by
     sending a crafted UDP packet containing empty data fields for client
     name or realm (boo#1071675)

   The following other bugs were fixed:

   - Override the build date (boo#1047218)
   - Use constant hostname (boo#1084909)
   - Handle long input lines when reloading database dumps
   - In pre-forked mode, 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.
