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)

CVE-2017-11368 :

In MIT krb5 1.7 and later, an authenticated attacker can cause an
assertion failure in krb5kdc by sending an invalid S4U2Self or
S4U2Proxy request.

CVE-2017-11462 :

RFC 2744 permits a GSS-API implementation to delete an existing
security context on a second or subsequent call to
gss_init_sec_context() or gss_accept_sec_context() if the call results
in an error. This API behavior has been found to be dangerous, leading
to the possibility of memory errors in some callers. For safety,
GSS-API implementations should instead preserve existing security
contexts on error until the caller deletes them.

All versions of MIT krb5 prior to this change may delete acceptor
contexts on error. Versions 1.13.4 through 1.13.7, 1.14.1 through
1.14.5, and 1.15 through 1.15.1 may also delete initiator contexts on
error."
