Description
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.
Notes
