The remote Amazon Linux AMI host is missing a security update.
Kerberos is a network authentication system which allows clients and
servers to authenticate to each other using symmetric encryption and a
trusted third-party, the Key Distribution Center (KDC).
A NULL pointer dereference flaw was found in the way the MIT Kerberos
KDC processed certain TGS (Ticket-granting Server) requests. A remote,
authenticated attacker could use this flaw to crash the KDC via a
specially crafted TGS request.
All krb5 users should upgrade to these updated packages, which contain
a backported patch to correct these issues. After installing the
updated packages, the krb5kdc daemon will be restarted automatically.

Run 'yum upgrade krb5*' to upgrade your system.
