Recent updates to the 389-ds-base packages on Red Hat address critical security vulnerabilities affecting enterprise-level Linux environments.
Updated 389-ds-base packages that fix one security issue are now available for Red Hat Enterprise Linux 6

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 https://access.redhat.com/site/articles/11258

Summary

The 389 Directory Server is an LDAPv3 compliant server. The base packages include the Lightweight Directory Access Protocol (LDAP) server and command-line utilities for server administration.
It was discovered that the 389 Directory Server did not properly handle the receipt of certain MOD operations with a bogus Distinguished Name (DN). A remote, unauthenticated attacker could use this flaw to cause the 389 Directory Server to crash. (CVE-2013-4283)
All 389-ds-base users are advised to upgrade to these updated packages, which contain a backported patch to correct this issue. After installing this update, the 389 server service will be restarted automatically.
