Description

Updated krb5 packages fix security vulnerabilities:

An issue was discovered in MIT Kerberos 5 (aka krb5) through 1.16. The 
pre-defined function "strlen" is getting a "NULL" string as a parameter value
in plugins/kdb/ldap/libkdb_ldap/ldap_principal2.c in the Key Distribution
Center (KDC), which allows remote authenticated users to cause a denial of
service (NULL pointer dereference) via a modified kadmin client
(CVE-2018-5710, CVE-2018-5729, CVE-2018-5730).
