Descriptions

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.

La función process_db_args en plugins/kdb/ldap/libkdb_ldap/ldap_principal2.c en el módulo LDAP KDB en kadmind en MIT Kerberos 5 (también conocido como krb5) hasta la versión 1.13.4 y 1.14.x hasta la versión 1.14.1 no maneja adecuadamente el argumento DB, lo que permite a usuarios remotros autenticados provocar una denegación de servicio (referencia a puntero NULL y caída de demonio) a través de una petición manipulada para modificar una principal.

A NULL pointer dereference flaw was found in MIT Kerberos kadmind service. An authenticated attacker with permission to modify a principal entry could use this flaw to cause kadmind to dereference a null pointer and crash by supplying an empty DB argument to the modify_principal command, if kadmind was configured to use the LDAP KDB module.
