The 389 Directory Server is an LDAPv3 compliant server. The base packages include the Lightweight Directory Access Protocol server and command-line utilities for server administration. It was discovered that the 389 Directory Server did not properly handle certain SASL-based authentication mechanisms. A user able to authenticate to the directory using these SASL mechanisms could connect as any other directory user, including the administrative Directory Manager account. This could allow them to modify configuration values, as well as read and write any data the directory holds. 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.
