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 honor defined attribute access controls when evaluating search filter expressions. A remote attacker (with permission to query the Directory Server) could use this flaw to determine the values of restricted attributes via a series of search queries with filter conditions that used restricted attributes. (CVE-2013-2219)

This issue was discovered by Ludwig Krispenz of Red Hat.

This update also fixes the following bugs:

  • Previously, the disk monitoring feature did not function properly. If logging functionality was set to critical and logging was disabled, rotated logs would be deleted. If the attribute "nsslapd-errorlog-level" was explicitly set to any value, even zero, the disk monitoring feature would not stop the Directory Server when it was supposed to. This update corrects the disk monitoring feature settings, and it no longer malfunctions in the described scenarios. (BZ#972930)

  • Previously, setting the "nsslapd-disk-monitoring-threshold" attribute via ldapmodify to a large value worked as expected; however, a bug in ldapsearch caused such values for the option to be displayed as negative values. This update corrects the bug in ldapsearch and correct values are now displayed. (BZ#984970)

  • If logging functionality was not set to critical, then the mount point for the logs directory was incorrectly skipped during the disk space check. (BZ#987850)

All 389-ds-base users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. After installing this update, the 389 server service will be restarted automatically.
