The 389-ds-base packages provide 389 Directory Server, which is an LDAPv3 compliant server. The base packages include the Lightweight Directory Access Protocol server and command-line utilities for server administration. A flaw was found in the way 389 Directory Server enforced ACLs after performing an LDAP modify relative distinguished name operation. After modrdn was used to move part of a tree, the ACLs defined on the moved were not properly enforced until the server was restarted. This could allow LDAP users to access information that should be restricted by the defined ACLs. This issue was discovered by Noriko Hosoi of Red Hat. These updated 389-ds-base packages include numerous bug fixes and enhancements. Space precludes documenting all of these changes in this advisory. Users are directed to the Red Hat Enterprise Linux 6.4 Technical Notes, linked to in the References, for information on the most significant of these changes. All users of 389-ds-base are advised to upgrade to these updated packages, which correct this issue and provide numerous bug fixes and enhancements. After installing this update, the 389 server service will be restarted automatically.
