CWEhttps://cwe.mitre.org/data/definitions/476.html

The prep_reprocess_req function in do_tgs_req.c in the Key Distribution Center (KDC) in MIT Kerberos 5 (aka krb5) before 1.10.5 does not properly perform service-principal realm referral, which allows remote authenticated users to cause a denial of service (NULL pointer dereference and daemon crash) via a crafted TGS-REQ request.

Weakness

The product dereferences a pointer that it expects to be valid but is NULL.
