Security issues fixed:
- CVE-2018-5730: DN container check bypass by supplying special crafted
 data (bsc#1083927).
- CVE-2018-5729: Null pointer dereference in kadmind or DN container check
 bypass by supplying special crafted data (bsc#1083926).
Non-security issues fixed:
- Make it possible for legacy applications (e.g. SAP Netweaver) to remain
 compatible with newer Kerberos. System administrators who are
 experiencing this kind of compatibility issues may set the environment
 variable GSSAPI_ASSUME_MECH_MATCH to a non-empty value, and make sure
 the environment variable is visible and effective to the application
 startup script. (bsc#1057662)
- Fix a GSS failure in legacy applications by not indicating deprecated
 GSS mechanisms in gss_indicate_mech() list. (bsc#1081725)");
