(RHSA-2012:1041) Moderate: redhat-ds-base security update

Red Hat 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 Red Hat Directory Server handled password
changes. If an LDAP user had changed their password, and the directory
server had 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 Red Hat 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 Red Hat Directory Server 8 are advised to upgrade to these
updated packages, which resolve these issues. After installing this update,
the dirsrv service will be restarted automatically.
