Scientific Linux Security Update : bind-dyndb-ldap on SL6.x i386/x86_64 (20120803)

medium Nessus Plugin ID 61426

Language:

Synopsis

The remote Scientific Linux host is missing one or more security updates.

Description

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.

Solution

Update the affected bind-dyndb-ldap and / or bind-dyndb-ldap-debuginfo packages.
