Synopsis: Moderate: 389-ds-base security update
Issue Date: 2012-06-20
CVE Numbers: CVE-2012-2678
 CVE-2012-2746

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.

A flaw was found in the way 389 Directory Server handled password changes.
If an LDAP user has changed their password, and the directory server has
not been restarted since that change, an attacker able to bind to the
directory server could obtain the plain text version of that user's
password via the "unhashed#user#password" attribute. (CVE-2012-2678)

It was found that when the password for an LDAP user was changed, and audit
logging was enabled (it is disabled by default), the new password was
written to the audit log in plain text form. This update introduces a new
configuration parameter, "nsslapd-auditlog-logging-hide-unhashed-pw", which
when set to "on" (the default option), prevents 389 Directory Server from
writing plain text passwords to the audit log. This option can be
configured in "/etc/dirsrv/slapd-[ID]/dse.ldif". (CVE-2012-2746)

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