openSUSE Security Update: Security update for libheimdal

Announcement ID: openSUSE-SU-2018:2376-1
Rating: important
References: #1047218 #1071675 #1084909
Cross-References: CVE-2017-17439
Affected Products:
openSUSE Leap 42.3

An update that solves one vulnerability and has two fixes
is now available.


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.
