Title:RedHat Update for bind-dyndb-ldap RHSA-2012:1139-01
Summary:The remote host is missing an update for the 'bind-dyndb-ldap'; package(s) announced via the referenced advisory.
Description:Summary:
The remote host is missing an update for the 'bind-dyndb-ldap'
package(s) announced via the referenced advisory.

Vulnerability Insight:
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)

Red Hat would like to thank Sigbjorn Lie of Atea Norway 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.

Affected Software/OS:
bind-dyndb-ldap on Red Hat Enterprise Linux Server (v. 6),
Red Hat Enterprise Linux Workstation (v. 6)

Solution:
Please Install the Updated Packages.
