CentOS 6 : bind-dyndb-ldap (CESA-2012:1139)

medium Nessus Plugin ID 61399

Language:

Synopsis

The remote CentOS host is missing a security update.

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.

Solution

Update the affected bind-dyndb-ldap package.
