Description :

The MIT Kerberos team reports :

CVE-2014-5353: The krb5_ldap_get_password_policy_from_dn function in
plugins/kdb/ldap/libkdb_ldap/ldap_pwd_policy.c in MIT Kerberos 5 (aka
krb5) before 1.13.1, when the KDC uses LDAP, allows remote
authenticated users to cause a denial of service (daemon crash) via a
successful LDAP query with no results, as demonstrated by using an
incorrect object type for a password policy.

CVE-2014-5354: plugins/kdb/ldap/libkdb_ldap/ldap_principal2.c in MIT
Kerberos 5 (aka krb5) 1.12.x and 1.13.x before 1.13.1, when the KDC
uses LDAP, allows remote authenticated users to cause a denial of
service (NULL pointer dereference and daemon crash) by creating a
database entry for a keyless principal, as demonstrated by a kadmin
'add_principal -nokey' or 'purgekeys -all' command.
