JSON

ec_verify in kdc/kdc_preauth_ec.c in the Key Distribution Center (KDC) in
MIT Kerberos 5 (aka krb5) before 1.18.4 and 1.19.x before 1.19.2 allows
remote attackers to cause a NULL pointer dereference and daemon crash. This
occurs because a return value is not properly managed in a certain
situation.
