    *Security fix*


  *  Addressed the log4j2 vulnerability: CVE-2021-44228


    Known issues and limitations

  * Kerberos server requires to be reconfigured using below CLI after
    update from 950 SP1 and PTFs. After update/upgrade from 950 to any
    newer HMC, if below scenarios via hscroot login are observed,
    reconfigure kerberos on HMC.

      o ls /etc/krb5.conf
        ls: cannot access '/etc/krb5.conf': No such file or directory
      o grep "kerberos.example.com" /etc/krb5.conf
        #   kdc = kerberos.example.com
        #   admin_server = kerberos.example.com

    Recommended CLI commands to reconfigure kerberos :
    *chhmc -c kerberos -s remove –realm <kerberos_hostname> -a
    <kerberos_ip>**
    **chhmc -c kerberos -s add --realm <kerberos_hostname> -a <kerberos_ip>
