Synopsis:    Important: bind-dyndb-ldap security update
Issue Date:  2012-08-03
CVE Numbers: CVE-2012-3429


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. (CVE-2012-3429)

All bind-dyndb-ldap users should upgrade to this updated package, which
contains a backported patch to correct this issue. For the update to take
effect, the named service must be restarted.
