CVE-2013-1416 WRITEUP WRITEUP
MIT Kerberos 5 < 1.10.5 - Authenticated Denial of Service via TGS-REQ Realm Referral
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.
CVE-2013-1417 WRITEUP WRITEUP
MIT Kerberos 5 < 1.11.4 - Authenticated Denial of Service via TGS-REQ Cross-Realm Referral
do_tgs_req.c in the Key Distribution Center (KDC) in MIT Kerberos 5 (aka krb5) 1.11 before 1.11.4, when a single-component realm name is used, allows remote authenticated users to cause a denial of service (daemon crash) via a TGS-REQ request that triggers an attempted cross-realm referral for a host-based service principal.
CVE-2013-1418 WRITEUP WRITEUP

The setup_server_realm function in main.c in the Key Distribution Center (KDC) in MIT Kerberos 5 (aka krb5) before 1.10.7, when multiple realms are configured, allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via a crafted request.
