NVD Description

Note: Versions mentioned in the description apply only to the upstream krb5-devel package and not the krb5-devel package as distributed by Centos. See How to fix? for Centos:6 relevant fixed versions and status.

The validate_as_request function in kdc_util.c in the Key Distribution Center (KDC) in MIT Kerberos 5 (aka krb5) before 1.13.6 and 1.4.x before 1.14.3, when restrict_anonymous_to_tgt is enabled, uses an incorrect client data structure, which allows remote authenticated users to cause a denial of service (NULL pointer dereference and daemon crash) via an S4U2Self request.
