3. Description:

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 certain Get Effective Rights (GER) search queries when the attribute list, which is a part of the query, included several names using the '@' character. An attacker able to submit search queries to the 389 Directory Server could cause it to crash. (CVE-2013-4485)

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.

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