"This update for krb5 fixes several issues.

This security issue was fixed :

  - CVE-2017-11462: Prevent automatic security context
    deletion to prevent double-free (bsc#1056995)

These non-security issues were fixed :

  - Set 'rdns' and 'dns_canonicalize_hostname' to false in
    krb5.conf in order to improve client security in
    handling service principle names. (bsc#1054028)

  - Prevent kadmind.service startup failure caused by
    absence of LDAP service. (bsc#903543)

  - Remove main package's dependency on systemd
    (bsc#1032680)

This update was imported from the SUSE:SLE-12-SP2:Update update
project."
