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