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.
Patch Instructions:
