Description
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.
A flaw was found in krb5. This flaw allows an unauthenticated attacker to cause a NULL dereference in the KDC by sending a request containing a PA-ENCRYPTED-CHALLENGE padata element without using FAST. The highest threat from this vulnerability is to system availability.
