Red Hat Security Advisory 2012-1139-01 - The dynamic LDAP back end is a plug-in for BIND that provides back-end capabilities to LDAP databases. It features support for dynamic updates and internal caching that help to reduce the load on LDAP servers. A flaw was found in the way bind-dyndb-ldap performed the escaping of names from DNS requests for use in LDAP queries. A remote attacker able to send DNS queries to a named server that is configured to use bind-dyndb-ldap could use this flaw to cause named to exit unexpectedly with an assertion failure.
