    Advisory URL:      https://rhn.redhat.com/errata/RHSA-2012-1139.html

    CVE Names:         CVE-2012-3429 
    =====================================================================
    
    1. Summary:
    
    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.
    
    2. Relevant releases/architectures:
    
    Red Hat Enterprise Linux Server (v. 6) - i386, ppc64, s390x, x86_64
    Red Hat Enterprise Linux Workstation (v. 6) - i386, x86_64
    
    3. 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)
    
    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.
    
    4. Solution:
    
    Before applying this update, make sure all previously-released errata
    relevant to your system have been applied.
    
    This update is available via the Red Hat Network. Details on how to
    use the Red Hat Network to apply this update are available at
