Summary
[none]
Details

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 kdcasrep function in kdc/kerberos5.c and the derlengthvisiblestring function in lib/asn1/der_length.c.
