Title:	RedHat Security Advisory RHSA-2012:0683
Summary:	NOSUMMARY
Description:	Description: The remote host is missing updates announced in advisory RHSA-2012:0683. 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 handled LDAP query errors. If a remote attacker were able to send DNS queries to a named server that is configured to use bind-dyndb-ldap, they could trigger such an error with a DNS query leveraging bind-dyndb-ldap's insufficient escaping of the LDAP base DN (distinguished name). This would result in an invalid LDAP query that named would retry in a loop, preventing it from responding to other DNS queries. With this update, bind-dyndb-ldap only attempts to retry one time when an LDAP search returns an unexpected error. (CVE-2012-2134) Red Hat would like to thank Ronald van Zantvoort for reporting this issue. 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. Solution: Please note that this update is available via Red Hat Network. To use Red Hat Network, launch the Red Hat Update Agent with the following command: up2date http://rhn.redhat.com/errata/RHSA-2012-0683.html Risk factor : High
