Patch  oval:com.redhat.rhsa:def:20121139
RHSA-2012:1139: bind-dyndb-ldap security update (Important)  

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.

Quick Help

Unknown Tests
There is a hardcoded maximum limit for number of tests displayed for a definition. For a small number of oval definitions, about ~1% of all, hundreds of test have been defined. This causes the pages to grow in size, exceed even 1mb, and they are unsuitable for display in a web page. So they are not displayed.Please refer to the xml definition files if you really want to view them.
