Description:	Summary: The remote host is missing an update for the 'libheimdal' package(s) announced via the referenced advisory. Vulnerability Insight: 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.
