CVE-2016-3119
Published: 26 March 2016
The process_db_args function in plugins/kdb/ldap/libkdb_ldap/ldap_principal2.c in the LDAP KDB module in kadmind in MIT Kerberos 5 (aka krb5) through 1.13.4 and 1.14.x through 1.14.1 mishandles the DB argument, which allows remote authenticated users to cause a denial of service (NULL pointer dereference and daemon crash) via a crafted request to modify a principal.
From the Ubuntu security team
It was discovered that Kerberos incorrectly handled certain requests. A remote authenticated attacker could possibly use this issue to cause a denial of service.
