## Description:

This update for krb5 fixes the following issues:

This update updates krb5 to 1.16.3 (jsc#PED-7884).

Most relevant changes:

  * Remove the triple-DES and RC4 encryption types from the default value of
    supported_enctypes, which determines the default key and salt types for new
    password-derived keys. By default, keys will only created only for AES128
    and AES256. This mitigates some types of password guessing attacks.
  * Add support for the AES-SHA2 enctypes, which allows sites to conform to
    Suite B crypto requirements.
