CVE ID:CVE-2017-17439
Description:In Heimdal through 7.4, remote unauthenticated attackers are able to crash the KDC by sending a crafted UDP packet containing empty data fields for client name or realm. The parser would unconditionally dereference NULL pointers in that case, leading to a segmentation fault. This is related to the _kdc_as_rep function in kdc/kerberos5.c and the der_length_visible_string function in lib/asn1/der_length.c.
Test IDs: 1.3.6.1.4.1.25623.1.1.10.2017.0485   1.3.6.1.4.1.25623.1.0.851856   1.3.6.1.4.1.25623.1.0.873987   1.3.6.1.4.1.25623.1.0.873993   1.3.6.1.4.1.25623.1.0.704055
