Affected configurations

• mit kerberos 5 (< 1.17.2) • mit kerberos 5 (>= 1.18.0 < 1.18.3) • fedoraproject fedora 31 • netapp active iq unified manager • netapp cloud backup • netapp oncommand insight • netapp oncommand workflow automation • netapp snapcenter • oracle communications cloud native core policy 1.14.0 • oracle communications offline mediation controller 12.0.0.3.0 • oracle communications pricing design center 12.0.0.3.0 • oracle mysql server (<= 8.0.23)
