Description


An updated bind-dyndb-ldap package that fixes one security issue is now
available for Red Hat Enterprise Linux 6.

The Red Hat Security Response Team has rated this update as having
important security impact. A Common Vulnerability Scoring System (CVSS)
base score, which gives a detailed severity rating, is available from the
CVE link in the References section.

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.
